Abstract :
In this paper, a communication scheme based on Gaussian minimum shift keying (GMSK) signal with trellis-coded modulation is presented. The coded/modulation scheme is an attractive technique for transmission of digital information over a bandwidth and power-limited channel. The coding gain of trellis codes provides power efficiency, and GMSK provides bandwidth efficiency due to the constant-envelope properties and good spectral features like all the CPM signals. In the receiver we propose an optimum detection Viterbi algorithm. Optimal trellis codes for the scheme can be found with computer simulation
