COMPENSATION OF MARKOV ESTIMATOR ERRORS IN TIME-JITTERED SAMPLING OF NONMONOTONIC SIGNALS

The so-called Markov estimator is sometimes used to estimate signals f rom their time-jittered samples [1]. The estimates are unbiased for mo notonic signals, but exhibit errors in regions of nonmonotonicity. A m ethod of compensation is presented to reduce this error. It requires a knowledge of the PDF of the time jitter, and a proposed method for de termining the PDF based on the generalized Markov estimator has been v erified through simulations. The performance of the compensation appro ach is presented for four different nonmonotonic waveforms.
