Abstract: A wireless receiver 200 and corresponding method 500 is arranged to mitigate the effects of non-ideal receiver processing and comprises: a signal source 202 for providing an injection signal that is controlled to have a unique frequency at each of a plurality of time periods; and a non-ideal receiver device 208 constructed to use the injection signal for down converting a received signal having a known frequency to collect a plurality of waveform samples, each having a desired characteristic that varies with the unique frequency and an undesired characteristic, wherein one of the plurality of waveform samples with the undesired characteristic removed will retain the desired characteristic of the received signal.
