ABSTRACT:
According to an embodiment of the invention, the information is transmitted in symbols encoded at a source to a destination. A log likelihood ratio is respectively calculated for each of the encoded symbols. The calculated log likelihood ratios for the information bits are accumulated where the contribution from each of the encoded symbols is accounted for in the accumulating step. Each of the information bits is decoded according to the accumulated log likelihood ratios. An acknowledgment (ACK) is sent to the source for each block of the decoded information bits that passed the error check. A negative acknowledgment (NACK) is sent to the source for each block of the decoded information bits that did not pass the error check. After the source receives the negative acknowledgment (NACK), the encoded symbols are retransmitted to the destination.
