<p>An apparatus and method (200) allow receivers to quickly acquire a pseudorandom noise signal. A receiver advantageously detects frequency shifts using a compact parallel process hardware implementation (202, 204, 208, 210) of a Discrete Fourier Transform (DFT)(208). The method applies a sequential test algorithm to the detection of a correlation signal. The method allows the receiver to search a range of frequency-time space relatively quickly.</p> |
