SYSTEM AND METHOD FOR IMPLEMENTING HYBRID AUTOMATIC REPEAT REQUEST USING PARITY CHECK COMBINING

摘要

The system has a transmitter (200), having a complete data packet which is divided into a number of data units (Dus) (200). The DUs (220) are encoded f or both error detection and error correction. Both the error correction and err or detection parity check bits are separately combined into one or more blocks. Thereafter, the DUs (220) and the block(s) containing the combined parity check bits are transmitted to the receiver (250). If the receiver (250) determines that a received DU (220) does not contain any errors, the error correction parity check bits for that DU (220) are generated and their effec t on the combined error correction parity check bits removed. Thereafter, the remaining error correction parity check bits, which now only contains information about the Dus (220) actually in error, are used to correct the erroneous Dus (220).
