On FM threshold extension by click noise elimination

The validity of the click noise method of S.O. Rice (1963) for describing the performance of an analog threshold-extending receiver is established within the scope of a simulated environment. The significance of the received signal envelope for enhancing the detection of clicks is examined, and it is shown that a reliable click detector must make use of signal memory. A 'genie-aided' errorless click detector could lower the FM threshold by at least 6 dB. Threshold extension of 2.75 dB is observed under simulated conditions, with a realizable, clicks-cancelling receiver at a modulation index of five.<
