Abstract:
1. A method for decoding a signal vector in a multiple-input multiple-output transmission scheme, comprising: receiving multiple signal vectors corresponding to a common digital information sequence, wherein the multiple signal vectors are received within distinct time intervals; decoding the received signal vectors, wherein decoding a given received signal vector comprises computing soft information for each of the bits in the given received signal vector based on channel information, associated with the given received signal vector; combining the soft information from each decoded signal vector to obtain an estimate of the digital information sequence; requesting retransmission of a subset of information associated with signal vectors received in a first time interval, wherein the subset of information is selected based on a per-bit reliability metric of the digital information sequence for signal vectors received in the first time interval; storing an estimate of the digital information sequence corresponding to signal vectors received in the first time interval; and combining an estimate of the digital information sequence corresponding to signal vectors received in a second time interval with the stored estimate corresponding to the signal vectors received in the first time interval.
