"A sphere decoder searches for the closest lattice point within a certain search radius. The search radius provides a tradeoff between performance and complexity," scientists in Alexandria, Egypt report.
"We focus on analyzing the performance of sphere decoding of linear block codes. We analyze the performance of soft-decision sphere decoding on AWGN channels and a variety of modulation schemes. A hard-decision sphere decoder is a bounded distance decoder with the corresponding decoding radius. We analyze the performance of hard-decision sphere decoding on binary and q-ary symmetric channels. An upper bound on the. performance of maximum-likelihood decoding of ...
