PROCESSING INTERFERENCE DUE TO NON-LINEAR PRODUCTS IN A WIRELESS NETWORK

摘要

Interference in a data stream carrying a plurality of uplink signals received in a wireless network is processed, the interference comprising a non-linear product (I3) of at least one downlink signal (C1) of the wireless network. The data stream carrying the plurality of uplink signals and at least a first data stream carrying a plurality of downlink signals is received, and data representing signals received at a first uplink carrier frequency is selected from the data stream carrying the plurality of uplink signals. Data representing signals at at least a first downlink carrier frequency is selected from at least the first data stream carrying the plurality of downlink signals. Interference is detected in the selected data representing signals received at the first uplink carrier frequency by correlation with a synthesized product generated from at least data representing signals at the first downlink carrier frequency.

1. A method of processing interference in a data stream carrying a plurality of uplink signals received in a wireless network, the interference comprising a non-linear product of at least one downlink signal of the wireless network, the method comprising:
receiving the data stream carrying the plurality of uplink signals and at least a first data stream carrying a plurality of downlink signals; selecting, from the data stream carrying the plurality of uplink signals, data representing signals received at a first uplink carrier frequency; selecting, from at least the first data stream carrying the plurality of downlink signals, data representing signals at at least a first downlink carrier frequency; and detecting interference in the selected data representing signals received at the first uplink carrier frequency by correlation with a synthesized product generated from at least data representing signals at the first downlink carrier frequency.
