A New ML-Based Iterative Timing Recovery Algorithm
Bangning Zhang · Signal Processing · 2008
The effects of symbol synchronization error on the LDPC decoding performance have been investigated. Then,A ML- Based iterative timing recovery algorithm is given,which seeks ask for proper symbol synchronization error to zero the derivative of the LLF. Simulation results show that the proposed method performs very close to the Cramer-Rao bound,and little performance degradation has been observed than the system with accurate symbol timing.
