A receiver and method for recovering transmitted symbols in a H-ARQ packet retransmission. The method includes receiving a communication signal; determining components of the signal that are not attributed to the desired symbols; removing the unwanted components from the signal to generate a modified communication signal; determining the effective channel impulse response for the modified communication signal; generating a block filter using the effective channel impulse response; and filtering the modified communication signal using the block filter to remove the inter-code interference in the modified communication signal and recover the desired symbols.
