Abstract :
This paper presents the results of a capacity evaluation for a cellular code-division multiple access (CDMA) system over a wideband fading channel. The study compares the performance of a system based on a conventional matched filter with that based on an adaptive receiver. Trellis codes and various rate convolutional codes are investigated in an attempt to improve the system performance. The performance is measured in terms of the maximum number of simultaneous users per cell for a given bit error rate (BER). The channel model is developed from measured propagation data at 2.6 GHz in heavily built-up urban areas and includes the effect of both intra-cell and inter-cell interferers
