Patent ID: 8300740

Claim:
A method of detecting a transmitted signal, the method comprising: generating a correlation signal from i) a received signal and ii) a spreading sequence; generating a magnitude signal from the correlation signal; generating a time-domain averaged signal based on i) the magnitude signal, and ii) at least a first time-delayed version of the magnitude signal delayed by at least one symbol period; generating a peak-to-average signal based on the time-domain averaged signal; wherein the generating the peak-to-average signal includes: generating a peak height signal based on the time-domain averaged signal, comparing the peak height signal to a peak height threshold, and setting the peak-to-average signal to a minimum value when the peak height signal does not exceed the peak height threshold; and processing the peak-to-average signal to determine whether the transmitted signal is detected in the received signal, including processing the peak-to-average signal after the peak-to-average signal has been set to the minimum value when the peak height signal does not exceed the peak height threshold.
