Abstract
The two equivalent closed-form expressions of the BER are presented for
an asynchronous DS-CDMA system using a maximal 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.
