Method and apparatus for reduction of intermodulation products

摘要

Interference to a received signal is reduced in a wireless network, the interference comprising intermodulation products of at least a first signal and a second signal. Delayed interference signals comprising simulated intermodulation products are generated on the basis of the first signal and the second signal using a range of differing delay values and each of the delayed interference signals is correlated with the received signal to produce data representing a correlation for each delayed interference signal. At least one delay value is selected in dependence on a the data representative of the correlations and an interference signal comprising simulated intermodulation products generated from the first signal and the second signal using the at least one delay value is combined with the received signal.

1. A method of reducing interference to a received signal in a wireless network, the interference comprising intermodulation products of at least a first signal and a second signal, the method comprising:
generating, on the basis of the first signal and the second signal, a plurality of delayed interference signals comprising simulated intermodulation products generated using a plurality of delay values; correlating each of the delayed interference signals with the received signal to produce data representing a correlation for each delayed interference signal; selecting at least one delay value of the plurality of delay values in dependence on a comparison of the data representative of the correlations; and combining, with the received signal, an interference signal comprising simulated intermodulation products generated from the first signal and the second signal using the at least one delay value.
