Abstract

Trellis coding of Gaussian minimum shift keying (GMSK) is considered. The structure of combinations of rate 1/2 and 2/3 binary convolutional encoders and GMSK modulation with several values of the parameter BT is studied by means of the so called “matched coding approach”. It is shown that in such connections up to 3 distinct classes of codes can be identified each with different receiver complexity. The results of the optimization procedure for codes combined with GMSK are given. The results show that significant coding gains (over 6.5 dB) are obtained. Power-bandwidth performance of the best coded schemes is presented where it is demonstrated that variation of BT offers another degree of freedom in the design of communication systems
