Abstract
A method includes determining an error vector magnitude for analog signals received by multiple antennas in an array of antennas of a base station, assigning quantization bits to a plurality of analog-to-digital converters (ADCs) of the base station such that some ADCs have different numbers of quantization bits allocated from a fixed total number of available quantization bits of the base station, and applying the analog signals to the ADCs with quantization bits assigned to reduce the error vector magnitude of the analog signals.
