- W2112542811 abstract "In orthogonal frequency division multiplexing (OFDM) system, synchronization and channel estimation are two important issues under the wireless fading channel in broadband wireless communication. The timing and frequency offset will affect the accuracy of channel estimation. These issues are studied in this paper, and a frequency selective fading channel under the OFDM system model is set up. This paper presents a cost function of combined estimation for timing synchronization, carrier synchronization and channel estimation, which is based on maximum likelihood. On this basis, a combined estimation algorithm using maximum likelihood is proposed. Simulation results show that the algorithm has high estimation accuracy and low system BER." @default.
