Blind estimation of symbol timing and carrier frequency offset in pulse shaping OFDM systems

چکیده

We introduce a blind algorithm for the joint estimation of s mbol timing and carrier frequency offset in pulse shaping 6FDM systems. The proposed estimator exploits the cyclostationarity of the received OFDM signal and can be seen as an extension of the Gini-Giannakis estimator (11 for single-carrier systems. An important feature of our method is the capability to perform a carrier frequency acquisition over the entire bandwidth of the OFDM signal. Furthermore, our estimator can be applied even if no cyclic prefix is used. We rovide simulation results demonstrating the performance orthe new estimator.

Timing Metrics of Joint Timing and Carrier-Frequency Offset Estimation Algorithms for TDD-based OFDM Systems

In joint timing and carrier offset estimation algorithms for Time Division Duplexing (TDD) OFDM systems, different timing metrics are proposed to determine the beginning of a burst or symbol. In this contribution we investigated the different timing metrics in order to establish their impact on the joint time and carrier-frequency offset estimation.
