Abstract :
This paper presents analytical expressions to evaluate the capacity of code division multiple access (CDMA) cellular radio systems employing a joint antenna array and a multiuser decorrelating detector. The performance is evaluated for chip-synchronous and asynchronous baseband and bandpass CDMA systems on additive white Gaussian noise and flat-fading Rayleigh channels. Simulation results have shown that the analytical model developed to evaluate the performance of those systems is a very tight approximation.
