Sampling jitter in full-duplex radio transceivers: Estimation and mitigation

In this paper, the problem of sampling-jitter estimation in OFDM full-duplex radio transceivers is addressed. The sampling-jitter estimation is very challenging, because the effects are very small, but still high enough to be a problem in full-duplex radios. The proposed sampling-jitter estimation method is based on estimating only the most significant frequency components of the sampling jitter. The performance of the estimation algorithm is evaluated with simulations by studying how much self-interference cancellation is achievable when the self-interference is mitigated using the estimates of the sampling jitter samples.
