Cochannelk interference canceler using a CMA adaptive array antenna

摘要

A CMA adaptive array is capable of extracting a single signal from multiple cochannels without a reference signal. However, the captured signal is not necessarily the desired signal. Also, since CMA is for a signal of constant envelope, the receiving characteristics degrades when the envelope of the signal changes, depending on the band limitation. This paper proposes a cochannel interference canceler which estimates the interference signal component in the received signal and eliminates interference com- ponent from the received signal.
