Abstract

A multichannel bandwidth-interleaved (BI) framework with digital back-end correction of mismatch errors is explored to simultaneously increase the sample-rate and bandwidth of the ADCs. In addition to the consideration of channel frequency-response mismatch and aliasing error associated with sampling, the autocorrelation matrix of magnitude response is introduced to evaluate the performance of overlapping cancellation between the nearby subbands. Simulation results and analytical calculations are provided to verify the efficacy of the proposed correction approach.
