摘要： In one embodiment, an HSDPA co-processor for 3GPP Release 6 Category 8 (7.2 Mb/s) HSDPA that provides all chip-rate, symbol-rate, physical-channel, and transport-channel processing for HSDPA in 90 nm CMOS. The co-processor design is scalable to all HSDPA data rates up to 14 Mb/s. The coprocessor implements an Advanced Receiver based on an NLMS equalizer, supports RX diversity and TX diversity, and provides up to 6.4 dB better performance than a typical single-antenna rake receiver. Thus, 3GPP R6 HSDPA functionality can be added to a legacy R99 modem using an HSDPA co-processor consistent with embodiments of the present invention, at a reasonable incremental cost and power.

摘要： A method and system for improving buffer compression in automatic retransmission request (ARQ) systems includes both a compander and decompander for further processing data. A received data string k bits in length is first companded according to a predetermined companding scheme. The companded data string is reduced to a length of k−1 bits for more efficient storage. Upon receipt of a request for retransmission, the stored companded data string is loaded and decompanded back to a length of k bits. Once decompanded, the data string is combined with a retransmitted data string to produce a single data string with an increased likelihood of being correct. By companding the data string before storage, a smaller memory block can be used for the storage of the data string.

摘要： In a communication method, data from a plurality of channels is combined into a composite channel by writing data from the plurality of channels as one-bit symbols to a memory, and reading out the data from memory to form the composite channel. The combining of radio frames from the channels forms a coded composite transport channel for transmitting the data in the downlink. To form the coded composite transport channel, an input process is initiated to write data for each radio frame of a transport channel as one bit symbols to a memory of an interleaver. On an output side of the interleaver, an output process to read out the data stored in the memory is performed to form the coded composite transport channel.
