Abstract

This paper analyzes the relationship of symbol synchronization error and carrier phase in OFDM system. According to this, a joint estimation algorithm is proposed. A matrix is reconstructed, and a linear fitting is completed by QR matrix decomposition. The symbol timing and carrier phase is got by this joint estimation. The simulation results show that in a certain condition, this algorithm has robust performance, especially in AWGN channel and Rayleigh fading channel with a strong multipath
