| Abstract: | Symbol synchronization in binary baseband PAM communication system is discussed in this paper. The system model is introduced and the probability of error in receiver as a function of symbol synchronization error is deduced.The bisection search algorithm based on maximun likelihood estimation for the estimation of the optimun timing phase is also developed. then, suggestion for further work is given by the authors. |
