Near-far resistance of space-time processing for wireless CDMA communications
W.Y. Xao, Charles L. Bernstein, Alexander M. Haimovich · IEEE Communications Letters · 1997
In this letter we evaluate the performance of space-time adaptive processing for wireless code-division multiple access (CDMA) communications through analysis of the near-far resistance. The model assumed is that of a frequency-selective and slow-fading channel. It is shown that while maximum ratio combining is not near-far resistant, optimum combining is near-far resistant when the number of cochannel interferences is less than the system dimensionality.
