Abstract

An H-ARQ system wherein the transmission of two consecutive, or sequential, blocks of information bits are considered jointly; i.e., one of the blocks of information being embedded within the other one of the blocks of information. If a retransmission for the first block is necessary, the system processes both blocks jointly. The system is provided with cross-packet coding which extends current H-ARQ schemes for point-to-point communications wherein the transmission of two consecutive block of information bits is considered jointly. If a retransmission for the first block is necessary, the system processes both blocks jointly. This allows both blocks to be decoded without errors at the receiver after the retransmission.
