Bit allocation for increased power efficiency in 5G receivers with variable-resolution ADCs
Bit allocation for increased power efficiency in 5G receivers with variable-resolution ADCs
In future mmWave wireless system, fully digital receivers may have an excessive power consumption at the Analog to Digital Converters (ADC), even if lower resolution ADCs are employed. We propose to optimize the ADC resolution exploiting the sparse propagation in mmWave. We identify and assign more bits to antennas that …
