摘要：
A spread spectrum signal sampled at a selected sampling rate is despread and accumulated in an accumulation element at a center frequency lower than the sampling rate and higher than zero. A frequency adjustment element may be used to adjust the accumulation element to have a resonant frequency approximately equal to the center frequency.
