Abstract: System and methods for reducing false alarm in the presence of random signals are disclosed. Various embodiments are operable to receive via a data interface a data block having at least one frame, normalize soft bits of the data block and re-encode decoder output bits of the data block, calculate a normalized correlation metric from the normalized soft bits and re-encoded bits of the data block, compare the normalized correlation metric to a threshold, and reject the data block when the normalized correlation metric is below the threshold.
