Abstract
Official abstract text for this publication.
A method, apparatus, and computer program for detecting sequences of digitally modulated symbols transmitted by multiple sources are provided. A real-domain representation that separately treats in-phase and quadrature components of a received vector, channel gains, and a transmitted vector transmitted by the multiple sources is determined. The real-domain representation is processed to obtain a triangular matrix. In addition, at least one of the following is performed: (i) hard decision detection of a transmitted sequence and demapping of corresponding bits based on a reduced complexity search of a number of transmit sequences, and (ii) generation of bit soft-output values based on the reduced complexity search of the number of transmit sequences. The reduced complexity search is based on the triangular matrix.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting sequences of digitally modulated symbols transmitted by multiple sources and received at a receiver, the method comprising: determining a real-domain representation that separately treats in-phase and quadrature components of a received vector, channel gains, and a transmitted vector transmitted by the multiple sources; processing the real-domain representation to obtain a triangular matrix; performing, at the receiver, a reduced-c…
