摘要: A narrowband interference (NBI) canceller is coupled to an A/D converter receive input signal and supply NBI-canceled error correcting decoder. In the NBI canceller, a first arithmetic unit receives predicted-interference signal, supplies difference thereof as interference-canceled signal. slicer decision second subtracts from generate noise coarse frequency estimator analyzes spectrum estimate of fundamental NBI. The used by adaptive predictor while adaptively tracking interference. Use in transceiver can eliminate link drop caused operation wireless devices that EMI cable.
