Abstract :
The authors analyze incoherent detection of trellis-coded continuous-phase M-ary FSK, using M quadrature receivers and trellis decoding. The upper bounds on the bit error rate as well as the 99% energy bandwidths are given for the codes under consideration. In particular, the authors consider trellis codes with rates of 1/2 and 2/3 with symmetric and asymmetric signal constellations. The upper bounds on the probability of error are obtained for symmetric and optimum asymmetric signal constellations. The optimum asymmetry is one which minimizes the probability of bit error. The performance of this system is compared with that of standard continuous-phase modulation techniques (MSK, duobinary, and TFM) using noncoherent detection
