Robustness of xampling-based RF receivers against analog mismatches

The analog imperfections in RF direct conversion receiver, of which I/Q imbalance is a major detriment, are examined. Existing literatures on I/Q imbalance compensation try to compensate for the imbalance by estimating the mismatches. In this work, xampling-based decoding algorithm is examined. This algorithm is shown to be very efficient in handling the impairments in the analog components. Simulation results are also presented to illustrate some of the benefits of the proposed approach.
