Spread Spectrum Mobile Radio Communications

Abstract

In this report, two problems are studied. The first is concerned with evaluating the performance of a class of bandwidth efficient modulation schemes in a frequency reuse mobile radio channel. The second problem is concerned with formulating and evaluating the performance of a class of known delay multipath diversity receivers for indoor wireless communication. Several partial response (PRCPM) schemes such as TFM, GMSK and 3RC are compared with regard to their performance in the presence of Adjacent Channel Interference (ACI) and CoChannel Interference (CCI). The performance criteria chosen were average probability of bit error and mean-square cross talk ratio. A comparison of three receiver filters with regard to their ability to reject ACI is also provided. Results indicate that receiver filter length is very important parameter for good performance. The performance of PRCPM schemes is analyzed by considering the combined effects of ACI, CCI and Rayleigh fading. The analysis is extended to the case when space diversity is employed. Results indicate that by using space diversity and maximal Ration Combining significant performance gains can be achieved. (RRH)
