Abstract: In digital communications, the symbol timing estimationis an very important element for high quality datadetection. This paper considers the problem of joint symboldetection and timing estimation, whose optimal solution is analytically intractable. In this paper, a stochastic M-algorithmis proposed for the solution. The stochastic M-algorithm is anovel efficient particle filtering algorithm designed for the discrete unknowns. To accommodate in the stochastic M-algorithm the continuous unknown symbol timing, the unscented Kalman filteris introduced, which leads to very efficient implementation. Thesimulation results illustrated that the stochastic M-algorithmachieves similar performance as particle filtering with only lessthan 1/25 of the complexity.
