Research
Wireless Communications with Low-Resolution Quantization
Wireless communication systems with low-resolution quantization are envisioned to be a major part of future wireless communication networks because of their potential to improve the energy efficiency of the network. This research project aims to conduct a comprehensive study on the performance impact of using low-resolution quantization at the receiver of wireless communication systems compared to traditional high-resolution systems. To that end, we study the optimum detectors and draw fundamental insights on the error probability performance of low-resolution quantization based wireless communication systems in the presence of fading and noise.
