Abstract:
A method for operating a wireless device, comprising steps of:(A) receiving a signal and decoding the received signal using a first predetermined decoding technique to generate a first received signal quality indication and a second received signal quality indication; (B) determining if the second received signal quality indication indicates one of a pass/fail condition; (C) if a pass condition is indicated, comparing the first received signal quality indication to a threshold value; and (D) if the first received signal quality indication is better than the threshold value, declaring the received signal to be a first type of received signal; else (E) if a pass condition is not indicated at Step C, or if the first received signal quality indication is found to not be better than the threshold value at Step D, decoding the received signal using a second predetermined decoding technique to generate a third received signal quality indication; (F) determining if the third received signal quality indication indicates one of a pass/fail condition; (G) if a pass condition is indicated at Step F, declaring the received signal to be a second type of received signal; else (H) if a fail condition is indicated at Step F, declaring the received signal to be invalid.
