短波猝发通信中的分数间隔均衡器研究
Research on Fractional Spaced Equalizer for Short Wave Burst Communication
摘要
Abstract
The short wave channel has characteristics of multipath,fading and time variant.In the equilibrium process,the convergence rate of Liner Equalizer(LE)is slow,the convergence precision is low,and the Fractional Spaced Equalizer(FSE)has better balance effect.So according to the waveform structure used in short wave burst communication,against the characteristics of short wave channel,this paper proposes a composite structure of T/4 FSE by employing Least Mean Square error(LMS)algorithm,Recursive Least Square(RLS)algorithm and square root Kalman algorithm.Simulation results show that in the short wave burst communication process,compared with traditional LE,the proposed FSE has faster balance speed and higher convergence precision.At the same time,the error characteristics of the communication system are significantly improved,which is more suitable for short wave channel.关键词
