| 摘 要： | 针对工频通信的信号特征及电网谐波的特性,采用数字差分技术,对信号进行检测,可以有效抑制电网整次谐波干扰.利用调制位置的不同,提出了多种信息编码方式,并利用信道的正交特性进行多通道同时传输,根据非整次谐波的特性,采用噪声最低的信道进行传输,从而保证传输可靠性.

| Abstract: | Based on character of signal in TWACS and harmonic in power system,the digital differential technique can detect the TWACS signal and eliminate the integer harmonics effectively.In this paper,considering the difference of modulate area,multi coding mode is presented.With the orthogonal character of channels,the scheme of multi signal channels is introduced.At the same time,to ensure the security of the signal transmission,the channel with the least noise strength can be used by the influence of non-integer harmonic. |
