Treffer: Low computing complexity frame synchronization for OFDM communication.

The paper deals with a new frame synchronization scheme for OFDM systems. The scheme is based on the computing of the detection window variance. The variance is computed in two delayed times, so a modified Early-Late loop is used for the frame position detection. The proposed algorithm has good properties regarding the choice of the algorithm's parameters since the parameters may be chosen within a wide range without having high influence on system performance. The verification of the proposed algorithm functionality has been performed on a development environment using universal software radio peripheral (USRP) hardware. The experimental results are compared to the simulation results, where the simulated system was an equivalent OFDM system with ideal time synchronization. [ABSTRACT FROM PUBLISHER]
