SUPPRESSION OF PULSE INTERFERENCE IN MULTIPATH CHANNEL USING RAKE CORRELATOR AND NON-LINEAR OPERATION

摘要

A modified (MD) Rake receiver for DS/SS signal from a slow Rayleigh fading multipath channel with strong pulse interference is considered with pulse blanking and pulse duration narrowing.this MD RAKE receiver can provide the anti-wide band pulse interference ability as well as the anti-multipath ability.The performance of blanking in MD Rake is analyzed.and an upper bound of bit error rate for the MD Rake with pulse width narrowing algorithm using linear predictor and pulse controlled Kalman algoritlwn is given under the derived pulse model which is suitable for many indnstrial pulse interferences.
