摘要：
In this paper we study the effect of random jitter in the sampling circuit at the receiver in an OFDM communication system. We show that the effect of jitter can be looked at as interference between different sub-carriers and derive a lower bound for the variance of the interference in terms of the eigenvalues of the covariance matrix of the jitter process. We compare the results with simulation results. We describe the effect of oversampling on the interference, and provide an explanation for the way interference varies with sub-carrier index for different sampling rates.
