摘要

Apparatus and method for correlating a received communication of a known sequence over a wireless channel. Processing at the required higher sampling rate is achieved through the use of a finite impulse response (FIR) filter (24) having a small number of taps for interpolating samples. This reduces hardware requirement by as much as one-half that of conventional techniques based on over-sampling the received signal, while obtaining amplitude degradation which is no worse than experienced when employing conventional techniques.
