Abstract: A speech signal is sampled (110) to form a sequence of speech data (300). The sequence of speech data (300) is segmented (120) into overlapping segments (310). Speech coefficients are generated (130) by fitting a waveform equation to each segment. The speech coefficients are quantized (140) to produce quantized coefficients. The quantized coefficients are run length encoded (150) to produce run length encoded coefficients. The run length encoded coefficients are Huffman coded (160) to produce Huffman encoded coefficients as compressed speech data.

Abstract: A method (100, 200), device (300) and microprocessor (400) are provided for selectively compressing video frames of a motion compensated prediction-based viedo codec based on a predetermined set of compression techniques. An energy estimate of the currrent displaced frame difference, DFD, is used to compute a ratio between the estimate and a historical mean of energy estimates. The ratio is iteratively compared to a predetermined set of thresholds which are associated with the predetermined set of compression techniques. The comparisons are used to choose a technique based on teh thresholds, and a technique is selected to be used for encoding the current DFD.

Abstract: An amplifier circuit (100) for use in a radio frequency system. The circuit is comprised of a first amplifier (22) having a first input (20) receiving a first signal (16) and a first output (24). A first coupler (18) samples the first input (20) of the first amplifier (22) and a second coupler (26) samples the first output (24) of the first amplifier (22). A third coupler (36) then compares an output of the second coupler (28) and an output of the first coupler (34), producing an error signal (38) which is substantially indicative of the difference between the first input (20) and the first output (24). A fourth coupler (44) combines the error signal (38) with a second signal (48) to produce a composite signal (50), the second signal (48) at least partially correlated with the first signal (16) received by the first input (20) of the first amplifier. A second amplifier (52) is responsive to the composite signal (50) and produces a second output (54).

Abstract: A system and method for registering a subscriber unit (10) in an integrated communication system having a number of subsystems (30, 50) that are capable of operating independently. The subscriber unit (10) stores in a memory (77) a list of outbound subsystems ordered according to the subscriber unit's preference for using the subsystem as a outbound home subsystem to which the subscriber unit (10) registers. An inbound preferred home subsystem list is also stored in the memory (77). In order to register to the integrated communicaton system, the subscriber unit (10) identifies the most preferred outbound subsystem that covers the current location of the subscriber unit (10) as its outbound home subsystem.

Abstract: A system for transmitting messages and multi-media presentations to a multi-media receiver (114). The system includes a multi-media messaging terminal (106) which has a controller (216) for the preparation and transmission of a multi-media presentation, composed of multi-media files. The multi-media files include user programmed text events (1258), graphics events (1260), audio events (1254) and multi-media commands (1256). The controller (216) is coupled to a memory, for storing the user programmed text events, graphics events, audio events and multi-media commands, and a multi-media interface (208). The multi-media interface (208) provides a interface to transfer the multi-media files being transferred from the multi-media terminal to a paging system. The paging system encodes multi-media files received with encoder (228) for transmission with transmitter (108).
