Performance analysis of cellular CDMA network based on smart antenna receiver

In this paper the performance of the uplink in the cellular CDMA network, based on the reception of a smart antenna, is analyzed in the frequency-selective fading channel. The analysis is under the asynchronous cellular CDMA system of multiple cells, in which BPSK modulation and RAKE combination based on smart antenna reception are employed. The closed-forms of the average error-probability are derived in this paper. The numerical results show that the performance of the cellular CDMA system based on a smart antenna is improved greatly; in addition, the final formula describes the inter-relations among BER, the user number of the system, the number of cells and fading model.
