Abstract
-
A noncoherent detection of a narrow band digital communication system employing channel coding with continuous-phase multilevel frequency modulation and Trellis decoding is analyzed. For the codes under consideration the power spectrum density function and 99% energy bandwidth are given.;In particular we consider rate 1/2 code with symmetric and asymmetric signal constellation. The upper bound on bit error rate is obtained for both cases. The results are compared with noncoherent detection of MSK and Duobinary signaling. It is shown that a symmetric signal constellation combined with a four states Trellis code offers no significant system performance improvement over a MSK signal. In addition, it is shown that an asymmetric signal spacing combined with a four states Trellis code gives a significant improvement over a MSK signal.
