Apparatus and method of detection for a packet-based wireless receiver employing multiple, concurrent transmitted streams

摘要

The present invention provides a packet detector for use with a packet-based wireless receiver employing a receive antenna for P concurrently transmitted streams, where P is at least two. In one embodiment, the packet detector includes a correlation unit coupled to the single receive antenna and configured to provide a correlation function based on P acquisition fields corresponding to the P concurrently transmitted streams. Additionally, the packet detector also includes a pseudo-magnitude calculator coupled to the correlation unit and configured to calculate a packet detection metric based on the correlation function.
