Patent ID: 8408475

Claim:
An apparatus, comprising: an input to receive a first signal, transmitted to the apparatus from at least one additional apparatus, from a communication channel; a demodulator to process the first signal to generate a first plurality of log-likelihood ratios (LLRs); a buffer, having a storage capacity less than all of the first plurality of LLRs, to store a first subset of the first plurality of LLRs that is less than all of the first plurality of LLRs; and an output to output a first plurality of hard decisions based on a second subset of the first plurality of LLRs; and wherein: the apparatus to transmit a re-transmission request to the at least one additional apparatus for the at least one additional apparatus to transmit at least one additional signal, corresponding to the first subset of the first plurality of LLRs stored within the buffer, to the apparatus; the input to receive a second signal, transmitted to the apparatus from the at least one additional apparatus, from the communication channel; the demodulator to process the second signal to generate a second plurality of LLRs; the buffer to store a first subset of the second plurality of LLRs; and the output to output a second plurality of hard decisions based on a second subset of the second plurality of LLRs.
