BANDPASS CORRELATION OF A SPREAD SPECTRUM SIGNAL. |
| 摘要 |
<p>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 (133) to produce a corresponding product output (135), and an accumulation output (137) is formed by combining the product output (135) with a phase-shifted version of the accumulation output (141).</p> |
