Abstract :
We extend previous work on linear MMSE (minimum mean square error) SISO (soft-in/soft-out) equalizers for turbo equalization to the case of fractional sampling of the received signal. We present a time-recursive algorithm also for this case. Special attention is paid to the influence of the receiver filter preceeding the sampler.
