METHODS AND DEVICES FOR DYNAMIC FILTER CONFIGURATION IN THE PRESENCE OF ADJACENT CHANNEL INTERFERENCE (ACI)

摘要

Apparatus and methods enable rejection of adjacent channel interference (ACI) in a way that mitigates reductions in performance, such as increased bit error rates, which might otherwise occur with conventional filtering algorithms used to combat ACI. For example, a filter or a filter stage may be shifted in frequency by an amount that corresponds to a measured power of the ACI. In some examples, the amount to shift the filter may correspond to a carrier to interference (C/I) ratio, which itself is based in part on the ACI. In some examples, the amount to shift the filter may further depend on the noise power in the wireless channel, since a lesser shift of the filter frequency may be beneficial in noisy environments.
