Adaptive cancellation of stationary interference in the presence of structured nonstationary interference

摘要

Adaptive linear cancellation of interference is a key technique for enhancing the performance of many current and planned radar and wireless communication systems. Present method of cancellation have limited capability when the interference is strongly nonstationary. A maximum likelihood-based cancellation procedure is give for Gaussian interference with a partially known nonstationary covariance component. This procedure is designed for adaptive cancellation implemented by a systolic cascaded array and performs well in computer Monte Carlo experiments.
