Squelch feature allows the users of a radio receiver to set a noise threshold such that a received signal is further processed only if the noise levels are below the set threshold. Modern communication receivers typically employ squelch feature in a DSP. In this paper, we describe a method for implementing a robust squelch algorithm using a Digital Signal Processor (DSP).
