TSP_by_SA

em algorithm - Find approximate solution to Sf = conv(s,f) = d using EM iteration. EM seeks to minimize the Poisson negative log likelihood function J(f) = sum_i {[Sf]_i - (d_i + sigma^2)*log([Sf]_i + sigma^2)}.

Turbo decoder under awgn channel. (The input is: uncoded bits,coded bits 1,coded bits2(interleaved), LLR from other source(if use only one turbo code ,fill all zero is ok), numbers of iterations, interleaver between two CC, source bit,decoder id(if used in parreled connected turbo codes), interleaver between two sources(under the situation of two turbo codes).)
