|Abstract:||A new scheme to study the performance of a DS/CDMA indoor wireless system, the correlation statistics distribution convolution (CSDC) modeling, is introduced in this paper. With the aid of the CSDC modeling, the bit error rate versus number of simultaneous interfering transmitters can be directly evaluated, considering the effects of Rayleigh fading, power control, multipath and co-channel interference. The performance of two CDMA receiver structures, conventional correlator and RAKE receiver, is compared. It is shown that the RAKE receiver is effective in improving the system performance under indoor multipath fading. However, its effectiveness under transmitter power control is sensitive to the severity of multipath interference in the indoor channel. When the multipath fading is severe, a tight power control over the main paths may not be able to improve the performance of the RAKE receiver.|
