K. Benletaief, EFFICIENT EVALUATION OF THE ERROR PROBABILITIES OF SPREAD-SPECTRUM MULTIPLE-ACCESS COMMUNICATIONS, IEEE transactions on communications, 45(2), 1997, pp. 239-246
In this paper, we consider the performance of code-division multiple-a
ccess (CDMA) communications, In particular, we will illustrate the use
of a semianalytical approach which is combined with importance sampli
ng for the efficient evaluation of the average bit-error rates (BER's)
of asynchronous direct-sequence (DS) based CDMA systems employing bin
ary phase shift keying (BPSK) modulation along with specific signature
sequences for a variety of system parameters.
