Abstract
An apparatus and method allow receivers to quickly acquire a pseudorandom noise signal. A receiver advantageously detects frequency shifts using a compact parallel process hardware implementation of a Discrete Fourier Transform (DFT). 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.
