A Spatial Domain Interference Canceller Using a Multistage Adaptive Array with Precise Timing Estimation

摘要

In SDMA, a spatial domain interference can- celler applying a multistage processing concept to the MMSE multibeam adaptive array has an attractive feature. Weak power signals strongly interfered can be detected in the succeeded stages after removing other strong power signals which are already de- tected. This idea can be enhanced to the reference timing es- timation required in the MMSE algorithm
