Repeat-punctured turbo trellis-coded modulation

In this paper repeat-punctured turbo trellis-coded modulation (RPTTCM) is proposed. In RPTTCM, the effect of repeat-puncture is investigated on a TTCM system, repetition of the information bits increases the interleaver size, followed by an appropriate puncturing scheme to maintain the respective code rate. The RPTTCM systems are simulated in an Additive White Gaussian Noise (AWGN) and the Rayleigh flat fading channel (with channel state information known at the receiver) will be used. The BER performance bound RPTTCM scheme is derived for both channels.
