Abstract :
Interleaved trellis coded systems with continuous phase modulation (TCCPM) are considered. It is shown that the combination of a trellis code, interleaver and the CPM modulator results in a significantly enhanced distance spectrum for the transmitted signals. Upper bounds on the bit error rate are derived by considering the combination of the trellis code, interleaver and the CPM modulator as serially concatenated code. Finally, iterative coherent and non-coherent receivers are proposed and their performance is evaluated through computer simulations
