摘要:
通过对对称三角线性调频（STLFM）信号在分数阶傅里叶域能量汇聚性的分析，提出了采用STLFM信号作为同步码，基于分数阶Fourier变换（FRFT）的正交多载波水声通信系统的联合同步算法，并以同步误码率（BER）作为评价指标，在有噪声、多径传输和多普勒效应三种环境组合下与传统OFDM系统采用线性调频（LFM）信号作为同步码进行仿真分析比较.仿真结果表明，在复杂的水声环境中，该算法在低信噪比时可以获得更精确的同步性能和更低的误码率.
Abstract:
By analyzing the symmetrical triangular linear frequency modulation (STLFM) signal has convergence of energy in the FRFT，the paper proposed using STLFM signal as the preamble to achieve orthogonal Multi-carrier underwater acoustic communication system joint synchronization algorithm with fractional Fourier transform (FRFT).Using bit error rate (BER) as the evaluation index，simulation analysis this algorithm and comparison with traditional OFDM system using linear frequency modulation (LFM) signal as the preamble in the environment with noise，multipath propagation and Doppler effect.Simulation results show that the more complex environment of underwater acoustic systems，STLFM signals as preamble can obtain the more accurate synchronization performance and the lower error rate.
