Abstract

The paper presents a method toa generate the ambient noise that characterizes the experimental data measured in a specific shallow water area by applying the FTR filter method. The parameter sets of the filter is examined by fitting the power spectrum density (PSD) of the noise from the simulation with that of the real noise by using the optimization algorithm Lp-norm method (LPNM). The results of ambient noise simulation show that the PSD trend removal of the generated noise is in agreement with that of the measured one. The paper also simulate a channel profile from the data along with LPNM method. The ambient noise from the simulation is added for the simulated channel for evaluating the system performance in term of symbol error rate (SER) values. The SER values are observed at different frequencies, different bandwidths and with different modulation schemes. The simulation results enable us to propose the frequency, the bandwidth as well as the modulation technique suitable to the system under the effects of the modeled ambient noise.

水下OFDM系统中的水下环境噪声模型及验证

本文提出了一种利用FTR滤波法在特定浅水区产生具有实验数据特征的环境噪声的方法。利用优化算法lp -范数法(LPNM)将仿真噪声的功率谱密度(PSD)与实际噪声的功率谱密度(PSD)拟合，检验滤波器的参数集。环境噪声仿真结果表明，产生噪声的PSD趋势去除率与实测噪声的PSD趋势去除率基本一致。本文还利用LPNM方法模拟了信道剖面。在仿真信道中加入仿真产生的环境噪声，以符号误码率(SER)值来评价系统性能。在不同的频率、不同的带宽和不同的调制方案下观察了SER值。仿真结果使我们能够提出在模拟环境噪声影响下适合系统的频率、带宽和调制技术。
