Abstract :
In this paper, several switching methods are presented for a class of switching turbo equalization, where the performance improvement is achieved via adapting the choice of equalizers during the iterative procedure. Four techniques for equalizer selection are presented and compared in computer simulations. The switching scheme based on the average soft information provided by SISO decoders showed the best bit error rate (1.5 dB processing gain at 10-4) with low complexity.
