Mitigation of narrowband interference in differentially modulated communication systems
Integration of RF/Analog and digital into a single chip can result in the coupling of digital spurs in the analog front end of a communication systems and can severely degrade the receiver performance. In this paper, we propose a novel receiver architecture of a notch filter together with the feedba...

| description | Integration of RF/Analog and digital into a single chip can result in the coupling of digital spurs in the analog front end of a communication systems and can severely degrade the receiver performance. In this paper, we propose a novel receiver architecture of a notch filter together with the feedback filter (FBF) of the decision feedback equalizer (DFE) to mitigate the impact of narrowband interference in differentially modulated communication systems without enhancing the inter-symbol interference (ISI). The proposed solution can be adapted to receiver architectures that employ either coherent or non-coherent demodulation of differentially modulated systems. Simulation results demonstrating the spur mitigation capability of the proposed solution is presented. |
