Hybrid Adaptive Feedback Nulling in the Presence of Channel Mismatch

摘要

This paper describes a hybrid feedback adaptive nulling technique which compensates for channel mismatch. Nulling systems often consist of a main channel and one or more auxiliary channels. In such systems the degree of nulling achieved is often limited by mismatched frequency responses between the auxiliary channels and the main channel. The hybrid feedback technique is shown to compensate for this mismatch by enclosing the mismatched receiver components inside an adaptive feedback loop.
