Embodiments of the invention provide a system and method of hybrid automatic repeat-request (HARQ) processing. A viterbi decoder is coupled to and follows a descrambler. After the signal has been de-scrambled, it can be stored in a memory in case it needs to be recombined with another packet. This means that the log-likelihood ratios LLRs for each transmitted bit are stored in memory using a finite number of bits (for example, between 4 and 12 bits). If the packet that is currently being processed contains retransmitted information, then the de-scrambled output stored from a previous packet containing the same information can be loaded and combined with the current packet. |
