ABSTRACT:
Interference in a wireless communication is minimized, or at least reduced, by scaling the symbols received from an interfering transmitter. Input samples from the interfering transmitter are isolated and decovered to generate received symbols. The gains of the received symbols are scaled to reduce the interference and the scaled symbols are covered to produce output samples that are spread to generate interference cancelled samples with reduced interference from the interfering transmitter. The function applied to scale the symbols may be linear or nonlinear.
