Sphere decoding (SD) algorithms for MIMO receivers can achieve similar performance to maximum-likelihood detection (MLD) algorithm with lower computational complexity. In general, channel decoding methods can achieve better performance if they are combined with soft-output SD rather than hard-output one. Unfortunately, not all soft-output values can be… CONTINUE READING
