SYSTEM AND METHOD FOR REDUCING FALSE ALARM IN THE PRESENCE OF RANDOM SIGNALS

摘要

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.
