Abstract
The two equivalent closed-form expressions of the bit error rate (BER) are presented
for an aysnchronous DS-CDMA system using a maxumal ratio combining diversity over a
Rician fading channel. The computational accuracy of the BER estimates evaluated by
these expressions is compared and verified through comparison with a semi-analytical
simulation result. It is shown mathematically that the BER formula, reduced to the
case of the well-known Rayleigh channel, is equivalent to the formula presented
previously.
