摘要
在OFDM传输系统的基础上,加入了一个OFDM-WATM信元发生器,组成了基于无线ATM的OFDM传输系统,以抵抗无线信道衰落和多径干扰带来的突发噪声和有效的利用频带资源.M atlab仿真理想环境下OFDM-WATM传输系统的各个部分性能,并给出接收端和发射端的仿真波形.
An OFDM transmission system based on Wireless ATM is formed by adding an OFDM-WATM cell transmitter to OFDM system, which is used to resist the burst errors caused by channel fading and multi-path interference in wireless system and makes full use of the bandwidth source efficiently. The performance of every part of the OFDM-WATM transmission system is analyzed and simulated by Matlab without any noise. The simulation signals at both receiving end and transmitting end are given.
