The Effectiveness of a Matched Filter to Cope with Harsh Continuous Wave EMI

In this paper, the effectiveness of a matched filter to cope with continuous wave – i.e. pure sinusoidal – EMI disturbances is studied. The bit-error-rate is taken as the metric to quantify the effect of the matched filter and compare this to the case when no matched filter is applied. It is seen that a matched filter becomes very effective when the frequency of the continuous wave equals an integer multiple of the sampling frequency or when the frequency of the continuous wave is significantly larger than the sampling frequency.
