Cyclostationarity-based Symbol Rate Estimation
Suhua Tang · Acta Armamentarii · 2005
Cyclic autocorrelation of common digital modulations was investigated, and the relationship between cyclic autocorrelation and delay as well as symbol rate was deduced, then a new estimation algorithm for symbol rates was presented in this paper. Theoretical analyses and simulations show that this new estimation method is characterized by lower computational complexity, less estimation error and independence of noise. The proposed algorithm is of practical value in modulation recognition and blind demodulation.
