Revisiting the timing and frequency offset estimation based on cyclostationarity with new improved method

Timing and frequency offset estimation based on the second order cyclostationarity have been explored in many literatures. In this article, we revisit the class of these estimators and propose for both single carrier and OFDM systems, a new method for timing and frequency offset estimation. Different from the previous methods, here, the estimation of timing and frequency offset process are independent of each other. Thus it does not introduce propagation error which is inherent in most of the estimators proposed so far and has an improved performance. Monte Carlo simulations are performed to verify the results.
