Power line communication is popular at indoor communication and smart home applications, which face a harsh using condition that is of bad impedance match, large signal attenuation, unexpectable noise and channel high time variation. These difficulties set a high threshold for power line communication technology and improve the communication channel simulation to an important place. To predetermine the performance of power line communication productions, a narrow-band communication simulation platform was developed. This platform is based on low voltage communication channel model, and can update the system parameters using on site measured data, which could get a match with the real application environment. Main channel characteristics, such as noise, signal attenuation and frequency respond could be simulated on this platform. Noise generation frequency range of this platform is 0~120MHz, attenuation frequency range is 0~4GHz and attenuation range is 0~120dB. All performance indexes can well cover the measurement boundary of power line communication.
