Abstract: A video processing system (100) employs a method and apparatus for indicating a location of a person (203) with respect to a video capturing volume (201) of a camera (101). A location determiner (115) receives at least one image from the camera (101), in which the image preferably includes at least a portion of the person (203). Based on the image, the location determiner (115) determines a location of the person (203) with respect to the video capturing volume (201) of the camera (101). An abstract representation generator (119) generates an abstract representation (209), e.g., an icon, of the person (203) and provides the abstract representation to a video processor (117). The video processor (117) positions the abstract representation (209) together with an image, e.g., of a remote call participant, to be displayed to the person such that the abstract representation indicates the location of the person with respect to the video capturing volume (201) of the camera (101), thereby providing processing and display efficient video feedback.

Abstract: A receiver unit (121) cancels interference in a composite received signal (102) by synthesizing a replica of the composite received signal which accounts for multipath effects (echoes) of the composite received signal. The receiver unit (121) is comprised of a RAKE receiver (122), which provides correlation peaks of the various multipath echoes. The correlation peaks are characterized by time delays and respective amplitudes and phases of the various multipath echoes. By generating a cancellation signal (124) which utilizes the correlation peaks of each multipath echo, a signal (130) more representative of the actual composite received signal is utilized to improve the degree of interference cancellation.

Abstract: An AMPS system facilitates reception and processing of a DS CDMA signal transmitted by a mobile station (125). The AMPS system provides an alternate path for the signal to be received by a DS CDMA receiver (506) system. The DS CDMA receiver system generates a signal compatible with the AMPS system, adjusts the generated signal to be proportional to the DS CDMA signal, and inputs the adjusted signal (510) into the AMPS system. The AMPS system then processes the adjusted signal for purposes of handoff of the mobile station (125) from the DS CDMA system to the AMPS system.

Abstract: A method and apparatus are provided for receiving electromagnetic radiation within a frequency band. The receiving is accomplished by intercepting electromagnetic radiation within the frequency band and converting the intercepted electromagnetic radiation into an electrical signal (102). Subsequently, a portion of the electrical signal (102) is digitized (104) into digitized signals (112, 113, 114). Each digitized signal (112, 113, 114) represents the intercepted electromagnetic radiation within a portion of the frequency band. Finally, a composite digitized signal (118) is generated (116) from at least two of the digitized signals (112, 113, 114). Alternatively, the receiving process may be enhanced by intercepting (188) first electromagnetic radiation (192) within a portion of the frequency band and by intercepting (190) second electromagnetic radiation (194) within another portion of the frequency band. Subsequently, the first and the second electromagnetic radiation (192, 194) is combined (196) into a composite electromagnetic radiation waveform (198). The composite electromagnetic radiation waveform (198) is converted into an electrical signal which may be processed (204) into digitized signals (206, 208) which form a composite digitized signal (118).

Abstract: A method and apparatus are provided for digitizing a wide frequency bandwidth signal (105). The digitizing is accomplished by separating the wide frequency bandwidth signal (105) into a plurality of narrow frequency bandwidth signals with a plurality of filters (110). Subsequently, a converter (120) generates digitized samples of the narrow frequency bandwidth signals. Finally, a composite digitized signal (160) is generated by a combiner (150) from the digitized samples which substantially represents the wide frequency bandwidth signal (105).

Abstract: An equalization system for equalizing a corrupted signal is disclosed. The equalization system includes a complex matched filter (400) and a maximum likelihood sequence estimator (MLSE) (405) for removing the effects of phase shift, amplitude variations, intersymbol interference, etc. resulting from multi-pathing and noise contributed by the receiver front end. The system estimates a correlation signal C(t) (505) and synchronizes C(t) (505) to maximize its energy as seen on the taps of the complex matched filter (400). Taps having amplitude coefficients below a predetermined threshold are set to zero to produce a modified CIR estimate. The modified CIR estimate which has had the effects of noise virtually eliminated, is then used to construct the complex matched filter (400) and is also used as input to the MLSE (405) to produce a better equalized data signal.

Abstract: The remote control system having symmetrical signalling circuits for radio communications is coupled to a single wire line/audio channel (26) and permits two or more units, base stations (12) and/or remote consoles (14), to be coupled to the single wire line. Each signalling circuit comprises a wire line coupler (48) for coupling to the wire line (26), an audio input (46) line and an audio output (44) line. An automatic gain control circuit (56) is coupled between the wire coupler (48) and the audio output (44) line and a filter (104) and line driver (106) are coupled between the audio input (46) line and the wire coupler (48). A control unit (70) including a microprocessor (71), a tone encoder (214), a tone decoder (210), a timer, a clock, and a memory (212) is coupled by output lines to the automatic gain control circuit (56) for controlling the modes of operation thereof which include a slow decay mode, a fast decay mode, an adapt mode and a hold gain mode. The output from the gain control circuit (56) is also routed through a bandpass filter (64) and a limiter (67) to the control unit (70). Further, the tone encoder (214) of the control unit (70) is coupled to a summing circuit (102) situated between the filter (104) and line driver (106) through a filter (97) and level control circuit (100). The protocol programmed in the microprocessor enables any unit to take control of the audio channel (26) by initiating the sending of a message. Also mute gates (60, 80) are provided for disabling audio output or audio input while a message is being sent or received over the audio channel (26).

Abstract: Orthogonal transmit diversity is implemented by employing a data splitter (803) to subdivide channel information (801) into at least a first portion of bits (802) and a second portion of bits (804). Each portion is spread with its own Walsh code for eventual transmission to a mobile station via a predetermined carrier frequency. When the number of bits in the first and second portion (802, 804) are small, separate Walsh codes are used to maintain orthogonality. When the number of bits in the first and second portion (802, 804) are relatively large, a time-division multiplex transmission is used to maintain orthogonality. A controller (809) controls the subdivision of the channel information and also an interleaver (308) to further enhance the effects of the diversity transmission. Control information related to the subdivision is transmitted to the mobile station so the channel information can be accurately reconstructed prior to decoding.

Abstract: To mitigate the adverse effects of the load imbalance phenomenon prevalent in spread spectrum, multi-carrier wireless communication systems, the system beneficially employs the use of handoff as a means for balancing the call traffic (commonly referred to as 'load') among a plurality of carriers within the communication system. The multi-carrier wireless communication system monitors (214) a plurality of metrics corresponding to the loading of each of the plurality of carriers in the communication system and, based upon the metrics, will handoff (220) call traffic to and between the plurality of carriers, thereby mitigating the adverse effects associated with the load imbalance, in accordance with the invention.
