Lp. Sabel et Wg. Cowley, PERFORMANCE ANALYSIS OF DECISION DIRECTED SYMBOL TIMING ESTIMATORS WITH DECISION ERRORS, Electronics Letters, 30(10), 1994, pp. 754-756
New results are given for the variance of optimum decision directed sy
mbol timing offset estimators when decision errors occur due to low si
gnal to noise ratios. The results, which may also be applied to symbol
timing phase detectors, are confirmed by simulation and compared to l
ower bounds.
