Abstract

Abstract

Non-Data-Aided (NDA) symbol synchronization for Orthogonal Frequency Division Multiplexing (OFDM) systems is studied in this paper. Firstly, a cost function, which is based on the power difference between adjacent subcarriers of OFDM system with constant modulus signaling, is proposed by assuming that the adjacent subcarriers have the same channel frequency responses. And a NDA symbol synchronization algorithm is proposed by minimizing the cost function. Secondly, two similar cost functions are proposed. The complexity and the influence of carrier frequency offset and channel noise on the proposed algorithm are analyzed too. Finally, the performance of proposed algorithm is analyzed by computer simulation with different cost functions and different carrier frequency offset. The simulation results show that the proposed algorithm outperforms generally obviously two others previously algorithms.
