Manimohan, VB and Fitzgerald, WJ (1999) Blind frequency synchronisation for OFDM systems with pulse shaping. IEEE International Conference on Communications, 1. pp. 178-181. ISSN 0536-1486Full text not available from this repository.
In multi-carrier systems, small carrier frequency offsets result in significant degradation of performance and this offset should be compensated before demodulation can be performed. In this paper, we consider a generic multi-carrier system with pulse shaping and estimate the frequency offset by exploiting the cyclostationarity of the received signal. By transforming the time domain signal to the cyclic correlation domain we are able to estimate the frequency offset without the aid of pilot symbols or the cyclic prefix. The Bayesian framework is used to obtain the estimate and we show how we can simplify the estimation process. © 1999 IEEE.
