Systems, devices, and methods are provided for mixed-mode signal processing that achieves unprecedented levels of out-of-band and in-band interference suppression. Embodiments of the present disclosure mitigate the effects of blockers and jammers, which have surfaced as issues in emerging cognitive radio systems as those networks struggle to co-exist with licensed and unlicensed users.

Described herein are various technologies relating to processing a coherent signal. A receiver is configured to receive an analog signal, and process the analog signal to generate an input analog signal. The input analog signal has been modulated according to a suitable modulation sequence. A coherent signal sampler coherently samples the modulation sequence, and the result of such sampling is in turn used to demodulate the input analog signal. The resultant signal is then passed to a sigma delta modulator, where it is converted to digital form.
