ABSTRACT
We have demonstrated that by using an adaptive space-time array the interference from multiple, strong interferers plus multipath can be cancelled down close to the noise floor without producing serious loss or distortion of a GPS signal. Design criteria are presented and limitations are examined. We also compare space-time processing with suboptimum space-frequency processing, and demonstrate by simulation that for equal computational complexity space-time processing slightly outperforms suboptimum space-frequency processing.
