Abstract :
We extend the single channel adaptive linear receiver (ALR) to the multidimensional case. The extension is used for the cancellation of strong spatially-distributed narrowband interference in direct sequence spread spectrum communications. Simulations show a gain of 8 dB for the case of two interferences occupying 30% of the bandwidth of the spread spectrum signal
