A New Technique for Performance Improvement of Mobile Radio Systems

In this paper a new technique for improving quality of signal transmission over mobile radio channels with flat fading of Rayleigh statistics, is suggested. It is the technique based on implementation of 16QAM trellis modulation. After an original analytical model for such signal processing scheme is defined, the mobile radio system performance are determined through calculation of bit error rate at the system output. It is shown that the technique proposed in this paper enables better received signal quality in comparison with other known techniques such as diversity reception with various combination methods or trellis coding with phase- shift keying modulations.
