WIRELESS COMMUNICATIONS DEVICE INCLUDING PATH SEARCHER WITH COMMON COHERENT CORRELATOR AND RELATED METHODS

摘要

A wireless communications device (30) may include a path searcher (31) for detecting signal peak locations in a received signal. The path searcher (31) may include a common coherent correlator (40) for performing a common coherent correlation operation on the received signal, and a plurality of peak detection frequency bin correlators (46a-46p) may be arranged in parallel downstream from the common coherent correlator. The wireless communications device (30) may further include a RAKE finger stage (32) for determining symbol values from the received signal based upon the detected signal peak locations.
