Fast Algorithm for Symbol Rate Estimation
Suhua Tang · IEICE Transactions on Communications · 2005
The cyclic autocorrelation of common digital modulation is researched, and the relationship between the cyclic autocorrelation and the delay, corresponding to the symbol rate, is deduced, then a searching algorithm for the symbol rate is proposed. Theoretical analyses and simulation results show that this method has less computation complexity and is also quite accurate. The estimation result is almost immune to the stationary noise. It's of practical value to modulation recognition and blind demodulation.
