A novel and improved apparatus for a wireless communication device, which provides fast detection and validation of pilot signals while minimizing the probability of false detection. In the apparatus a searcher subsystem generates a pilot energy sample corresponding to a pilot signal, which is provided to a pilot signal detection filter, comprising two parallel branches. The first branch calculates a weighted historical average of a signal strength of the pilot signal in response to the pilot energy sample, the second branch verifies the pilot energy sample in a state machine, wherein transitions of the state machine are proportional to a magnitude of the pilot energy sample. A pilot detection signal is generated if either the weighted historical average exceeds selected threshold, or a state of the state machine exceeds a maximum value of the states.
