Abstract
A receiver for receiving and decoding a carrier signal is described. The carrier signal is modulated with a digital signal. The receiver includes a receiver section (162) for demodulating the received carrier signal. The demodulated signal is then sent through an A/D converter (164) for converting the demodulated signal into a digital format. A digital signal processor (166) receives the digital format and calculates the autocorrelation function of the digital format. The digital signal processor (166) then computes the ratio of the autocorrelation at two different reference points and compares this value to a plurality of values stored in its memory locations. The plurality of stored values representing different signal quality measurements.
