Abstract :
This paper investigates the performance and capacity of space time block coded (STBC) multi-user CDMA system over Rayleigh fading channel condition using multiple transmit antennas. Using simulation and analytical approach, we show that STBC CDMA system has increased performance in cellular networks. We also compare the performance of this system with the typical CDMA system and show that STBC and multiple transmit antennas for multi-user CDMA system provide performance gain without any need of extra processing or bandwidth.
