On the Capacity-Achieving Input of the Gaussian Channel with Polar Quantization
Neil Irwin Bernardo, Jingge Zhu, Jamie Evans
The polar receiver architecture is a receiver design that captures the envelope and phase information of the signal rather than its in-phase and quadrature components. Several stud…
Capacity Bounds for One-Bit MIMO Gaussian Channels with Analog Combining
Neil Irwin Bernardo, Jingge Zhu, Yonina C. Eldar +1
The use of 1-bit analog-to-digital converters (ADCs) is seen as a promising approach to significantly reduce the power consumption and hardware cost of multiple-input multiple-outp…
