Abstract :
This paper studies diversity combining techniques in the GSM based systems. A pre-detection maximal-ratio diversity receiver for GSM is presented. It is an optimum diversity demodulator for band-limited channels with Gaussian noise and intersymbol interference. The performance of diversity combining techniques is studied in the GSM data channel. The effects of correlation between diversity channels is also studied. The best diversity combining technique is found to be the presented pre-detection maximal-ratio technique
