Geometric Decoding Of PAM and QAM Lattices

Abstract

A geometric decoding technique for finite lattices was presented by Seethaler et al. for flat-fading multiple-input multiple-output channels in the case of linear modulations with constant amplitude (PSK). In this paper, geometric decoding is extended to square PAM and QAM constellations. Geometric decoding is suboptimal but has the advantage that the… (More)
