【摘要】 双向工频通信技术(TWACS)是一种基于电力配电网络的新型通信技术,具有独特的调制解调机理。由于其调制信号的特殊性,很适合差分曼彻斯特编码。将相邻周期的幅值作差,经过4阶IIR滤波后,结合数理统计方法能够可靠地识别信息。更多还原

【Abstract】 TWACS is a new valuable communication technology for distribution networks, which has special principle of modulation and demodulation. Differential Manchester code is fit for TWACS according to the speciality of modulation signal. Subtracting amplitude of every adjacent period, and the result passes through a four steps IIR filter, the information can be identified, cooperated with statistic technique.更多还原
