Bandpass correlation of a spread spectrum signal |
摘要 |
A spread spectrum signal is processed after it is sampled at a selected sampling rate and tuned to a center frequency lower than the sampling rate and greater than zero. The signal is multiplied against a reference signal to produce a corresponding product output, and an accumulation output is formed by combining the product output with a phase-shifted version of the accumulation output.
