Frequency selective fading model on near-far problem in M-ary CDMA communication

The data transmission performance of the M-ary code division multiple access (CDMA) system is evaluated by the wide-band propagation simulator (WBPS). The WBPS for multiple users is based on the authors' frequency selective fading (FSF) model. It is shown that the FSF model is affected by the time-variant characteristic of the propagation path and the near-far problem.
