Abstract :
Interleaved trellis coded systems with continuous phase modulation (TCCPM) are considered. Upper bounds and lower bounds on the bit error rate (BER) performance are derived for coherent detection on the additive white Gaussian noise and flat Rayleigh fading channels by considering the trellis code, interleaver and CPM modulator as a serially concatenated convolutional code. A coherent receiver that performs iterative demodulation and decoding is shown to provide performance close to the lower bounds developed.
