Compensation of Sampling Jitter Effect in Radio Frequency Sub-Sampling Receiver

Subsampling receivers are able to down convert signals from radio frequency (RF) to a lower frequency by exploiting intentional aliasing. The implementation of subsampling method in Software Defined Radio (SDR) reduces the sampling frequency requirement in Analog to Digital Converter (ADC).However,...
