Open publisher page 1 citations

Abstract

An improved carrier frequency-offset estimation method and a channel estimation method,jointed with a high precision symbol timing synchronization method are proposed.So the performance of the system is increased greatly.In this paper,an OFDM underwater communication system is designed.At the same time,the simulink with that system are done and its performance is analysed.
