The adaptation receiver filter, signal strength and bit error rate detection were used, interference reduction manner

摘要

A radio receiver having a variable bandwidth received channel filter (113, 115) to reduce interference is disclosed. An interference is detected by comparing received signal strength and received signal BER. The bandwidth of the filter (113, 115) is narrowed to improve BER when a received signal strength is greater than a threshold value and BER is worse than a threshold value.
