Abstract: The present invention teaches of a method of encoding linear predictive coefficient data. The present invention transforms the linear predictive coefficient data into line spectral cosine data (103). The line spectral cosine data is used to generate two recursively defined vectors (104). The recursively defined vectors are used to compute a set of sensitivity autocorrelation values (106a-106N) and a set of sensitivity cross correlation (107a-107N). The line spectral cosine values are used to compute a set of line spectral square root values.

Abstract: The present invention involves demodulating a signal in a spread spectrum multiple access system employing a pilot on the foward link. The rake receiver (10) separates the signal processing based on the period over which the processing occurs. Symbol rate processing is performed by a single time-shared mutiply-accumulate datapath (34) that services multiple finger front ends (312) and a searcher front end (314). The front ends (312) are dedicated circuits that perform all chip rate processing, producing a data vector and asserting a flag indicating the results are ready to be serviced by the shared datapath. A datapath controller (308) arbitrates use of the datapath between the finger front ends (312), the searcher front end (314), and combining functions, configuring the datapath to service them on a first-come, first-serve basis. The controller (308) sequences the datapath through a fixed routine as dictated by the signal processing associated with the block being serviced.

Abstract: A method and apparatus of determining signal strength, regardless of the signal data rate, in a receiver receiving signals from a variable rate transmitter. The incoming signal is comprised of a series of frames. Each frame is comprised of a number of power control groups containing data. The number of the power control groups containing data within each frame is dependent on the unknown data rate. The position of the power control groups within the frame is a pseudorandom. The signal strength of an incoming signal of unknown data rate is determined based upon an active set of power control groups within a frame. The active set of power control groups contain data independently of the unknown data rate. The signal strength information may be used to indicate that the signal strength is sufficient to perform further signal processing.

Abstract: A double helix antenna (10) comprised of orthogonally-wound helix conductors. The double helix antenna (10) includes a first helix conductor (14) wound in a first direction about a vertical axis, V, of the double helix antenna (10). A second helix conductor (18) is wound in a second direction about the vertical axis, V. In a specific implementation, the first and second helix conductors (14 and 18) are of different lengths, respectively corresponding to first and second frequency bands. Additionally, the first and second helix conductors (14 and 18) are wound so as to be orthogonal at those horizontal planes within which the first and second helix conductors (14 and 18) intersect or are otherwise minimally separated in the horizontal dimension. This orthogonal winding relationship between the helix conductors substantially reduces mutual coupling, thus enabling operation of separate helical antennas in close physical proximity.

Abstract: A wireless telephone system (106) having digital signal processing capability determines if a telephone call is directed to a public switched telephone network (100) (PSTN) located within a local calling area having another wireless telephone system. If so, an asynchronous transfer mode (ATM) or other packet based link (104) is established between the two wireless telephone systems, and vocoded audio information is transmitted over that ATM link. Upon reaching the second wireless telephone system the vocoded audio information is converted by the second wireless telephone system (106) into pulse code modulation (PCM) encoded audio information, and introduced into the PSTN (100). On the reverse path, PCM formatted data from the receiving PSTN (100) is converted into vocoded audio information by the second wireless telephone system (106), and then transmitted to the first wireless telephone system (106) via the ATM or other packet based link (104).

Abstract: A method and apparatus for providing a reliable means to perform handoff from a code division multiple access (CDMA) system using a pilot signal to an alternative access technique system. Simple pilot box circuitry (350) is added to a set of border base stations (C2A - C2R). The border base stations (C2A - C2R) are base stations which operate only in the alternative access technique and which have coverage areas which are contiguous with coverage areas of CDMA operation base stations. The mobile unit monitors for the pilot signal from the border base stations (C2A - C2R) in the same manner as it monitors for pilot signals from the CDMA operation base stations (C1A - C1s). When the mobile unit detects the pilot signal corresponding to a border base station (C2A - C2R), it notifies a system controller (202) in accordance with standard operation. The system controller (202) is aware that the pilot signal corresponds to a border base station (C2A - C2R) and thus triggers a hard handoff process to the alternative access technique system in response thereto.

Abstract: A cellular radiotelephone (100) which uses voice feedback to announce which key of the keypad (155) has been depressed or to indicate the status of radiotelephone (100). The voice signals for the feedback are stored in memory (150) in a digitized and compressed format. The radiotelephone's speech CODEC (140) decompresses the appropriate digital signal. The CODEC (140) transforms the digital signal to an analog voice signal for use by the radiotelephone's audio output device.

Abstract: The filter of the present invention pre-processes signaling messages transmitted by the base station while the radiotelephone is in the idle mode. The radiotelephone informs the filter of the roam status and idle status and identity of the radiotelephone. The filter then intercepts the incoming signaling messages while the processor is in the sleep mode conserving power. When the filter detects a message requiring further processing by the processor, the filter interrupts the processor to process the message.

Abstract: The dual band code division multiple access radio of the present invention operates on multiple frequencies simultaneously on either transmit or receive. The transmit path operates by splitting the transmit intermediate frequency (IF) path (103) and mixing the IF to two different transmit frequencies using two frequency synthesizers (140 and 145). The receive path (104) has two RF channels (116 and 117) that are mixed with the frequencies generated by the synthesizers (140 and 145) and summed into one IF strip. Thus the radio of the present invention can perform a soft hand-off between frequencies while communicating with both base stations simultaneously. Additional mixing paths and synthesizers can be added if it is desired to communicate with more than two base stations simultaneously.

Abstract: A novel and improved method of acquisition in a spread spectrum communication system is presented. In the present invention, a large window of PN chip offset hypotheses are searched which are generated by a PN sequence generator (20) under the control of a searcher controller (18). The energy of the despread sequence which is despread by a despreader (6) is found that might indicate the presence of the pilot signal in a threshold comparer (16) having one of the chip offsets of the large search window, then a search of a subset of offset hypotheses, or small window, is searched under the control of searcher controller (18).
