acit ita1 Cellular CDMA System With Adaptive Receiver
Ian Oppermann, Branka S. Vucetic, Predrag Rapajic · 2006
This paper presents the results of a ca- pacity evaluation for a cellular code-division, multi- ple access (CDMA) system over a wide-band fading channel. The study compares the performance of a system based on a conventional matched filter with that based on an adaptive receiver. T rellis codes and various rate convolutional codes are investigated in an attempt to improve the system performance. Perfor- mance 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 mea- sured propagation data at 2.6 GHz in heavily built-up urban areas and includes the effect of both intra-cell and inter-cell interferers,
