Abstract :
Feedforward symbol timing recovery techniques are widely used in burst-mode transmission systems. In this paper, a timing estimation method that uses two samples/symbol sampling rate is investigated. We provide a theoretical justification for the algorithm and present the variance of the timing estimate for different parameters including roll-off factor and estimation interval length. The timing estimation performance of a modified version of the algorithm is also investigated. Some of the implementation issues are discussed.
