基于正交频分复用(OFDM)技术和反相对称法(PISM)的基本原理,将二者结合,设计了一种PISM-OFDM通信系统,并用MATLAB软件进行了仿真研究,证实了其在抗干扰方面具有一定的优势。
This paper first introduces the fundamentals of the OFDM and PISM(Phase Inversion Symmetric Method).Then combining the two techniques,we design a new communication system PISM-OFDM.Finally,using the Matlab,we analyze and study the new system performance,proving that it has certain advantages in anti-interference.
