Abstract
Official abstract text for this publication.
Systems and methods are provided for decoding signal vectors in multiple-input multiple-output (MIMO) systems, where the receiver has received one or more signal vectors from a common digital information sequence. Each received signal vector is decoded using, for example, a maximum-likelihood decoder to produce log-likelihood ratios. The results of the decoders are combined by addition to produce a final decoding estimate. In some embodiments, each of the received signals may be processed prior to decoding. The disclosed decoding scheme may utilize all received information without increasing hardware complexity.
First claim
Opening claim text (preview).
What is claimed is: 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 ba…
