【摘要】 本文用统计的观点研究了电力线信道幅频特性的多径拟合并运用Matlab工具对中压电力线信道的幅频特性进行了较为精确的拟合,有利于在系统设计和性能评估中采用多径模型进行信道模拟。文中给出了1～30MHz频率内中压电力线信道上的实测幅频特性与多径模型加权及不加权最小均方拟合结果的比较。更多还原

【Abstract】 This paper studies the statistic curve fitting for the amplitude—frequency response of Medium-Voltage(MV) power line using multipath model.It is seen that the power cable attenuation can be well characterized by this method,and therefore,it is suitable for the system performance evaluation.The satisfactory agreement between actual measurements on MV channel and theoretical modeling within 1～30MHz using the weighted least-square error criterion are also presented.更多还原
