The effectiveness of different diversity combining techniques in improving the bit error rate (BER) performance of a direct-sequence code-division multiple-access (DS-CDMA) system is presented in this paper. The overall performance of a DS-CDMA system is degraded by multipath fading and additive white Gaussian noise (AWGN). To evaluate the degradation, the expression for the conditional BER, conditioned...
The effects of multipath fading and additive white Gaussian noise (AWGN) on the bit error rate (BER) performance of direct-sequence code-division multiple-access (DS-CDMA) systems is studied in this paper. The expression for the conditional BER, conditioned on a given level of fading is derived and then the unconditional BER is evaluated. The BER performance results of the system are evaluated in...
