Abstract
A wireless receiver is disclosed. The wireless receiver includes a phased array antenna panel having a plurality of antennas, and a low resolution analog-to-digital (A/D) converter coupled to each of the plurality of antennas, where the low resolution A/D converter is configured to provide a digital output based on comparing a reference value with a sum of noise value and signal value of an analog input received by the corresponding one of the plurality of antennas. Noise signals received by the plurality of antennas are uncorrelated, and a signal to noise ratio (SNR) of the analog input can be less than one. The low resolution A/D converter can be a one-bit A/D converter. The one-bit A/D converter can be a comparator receiving the sum of noise value and signal value as one comparator input, and receiving the reference value as another comparator input.
