基于MATLAB的PISM-OFDM系统仿真与分析
he Simulation and Analysis of PISM-OFDM System Based on MATLAB
正交频分复用(OFDM)是第四代移动通信的核心技术之一。本文首先分析了OFDM技术的基本原理,然后对其改进加入了反相对称法(PISM),设计了一种PISM-OFDM通信系统。用MATLAB软件对OFDM和PISM-OFDM两系统进行仿真分析与研究,给出了误码率曲线。仿真结果表明了在相同信道和相同信息速率的条件下,PISM-OFDM系统提高了抗干扰能力,证实了将反相对称法应用于OFDM中具有一定的优势。
Orthogonal Frequency Division Multiplexing (OFDM) is one of the techniques in the forth generation mobile communication. This paper first introduces the fundamental schematic of OFDM. Then based on it and with phase inversion symmetric method (PISM), we design a new communication system PISM-OFDM. Using the MATLAB, the SNR curves are given. We analyze and study the performance of the two systems, proving that with the same channel and the same information ratio, PISM-OFDM has certain advantages in anti-interference.
