Concatenated codes with interleaver for digital transmission over mobile channels

We present a codes with interleaver for digital transmission over mobile channels thorough comparison among three alternative solutions for the transmission of medium-high speed data over mobile telecommunication systems with high quality of service. They are based on concatenated codes with interleavers, the first two using the parallel concatenation known as turbo code, and the third the serial concatenation recently proposed. The comparison between the two alternatives has been based on the computation of the free distance of the resulting codes, and on extensive simulations over additive Gaussian noise (AWGN) and correlated multipath fading channels.
