VERSATILE SYSTEM FOR INTERFERENCE TOLERANT PACKET DETECTION IN WIRELESS COMMUNICATION SYSTEMS

摘要

The invention provides a system for obviating interference effects in packet detection within a wireless communications network. A plurality of reference signals is provided, a first of which corresponds to desired packets, and the remainder of which correspond to undesired packets or interference. A plurality of cross-correlation constructs corresponds, respectively, to the plurality of reference signals. Each cross-correlation construct (100) correlates an incoming signal to a plurality of repetitions of its respective reference signal. An analysis construct compares output from each cross-correlation construct with other cross-correlation construct outputs, and with a threshold value, to determine which incoming signal corresponds to desired packet data. Once this incoming signal is identified, packets from the signal may be reliably received.
