摘要
介绍了电力线通信网络技术,分析了低压配电网对信号传输衰减大、干扰强、阻抗变化复杂的信道特性,推出了采用改进的正交频分复用(OFDM)技术的双芯片电力线通信网络解决方案。
The technology of power line communication network (PLCN) is introdced and the transmission characteristics of low voltage power line system is analysed where signal attenuation, strong disturbance and complex variation of impedance exist. Then a dual chip PLCN solution is proposed in which advanced Orthogonal Frequency Division Multiplexing (OFDM) technique is adopted.
