Abstract

Faster than Nyquist (FTN) transmission is investigated for a point-to-point AWGN link. The FTN is interpreted as a form of coding at the pulse shape level, and accordingly, the so-called Mazo phenomenon is interpreted as a coding gain. Then, it is shown by simulation that such a gain can disappear in a coded FTN transmission with a powerful FEC code, such as turbo code. This result undermines the FTN transmission as an effective technique in an actual communication system.

涡轮编码单载波比奈奎斯特传输快
研究了点对点AWGN链路比Nyquist (FTN)更快的传输速度。FTN被解释为脉冲形状级的一种编码形式,因此,所谓的马佐现象被解释为编码增益。然后,通过仿真表明,在具有强大FEC码(如turbo码)的编码FTN传输中,这种增益可以消失。这一结果削弱了FTN传输在实际通信系统中作为一种有效技术的作用。
