Abstract :
We compare complexities and performances of some suboptimum linear and nonlinear (BLAST) interfaces used for decoding space-time codes used over a Rayleigh fading channel. We observe how the introduction of an interleaver can be beneficial here. We introduce a new simple iterative linear interface, based on hard Viterbi decoding and offering a performance considerably improved with respect to noniterative receivers.
