摘要
文章搭建了两种OFDM通信系统模型,采用MATLAB语言仿真了整个系统并得到了相应仿真结果,在此基础上对OFMD系统在八种信道模型、三种信道估计算法下的性能做了更全面而深入地分析,获得的结论有助于我们在面对不同的环境下选择怎样的信道估计算法提高通信系统整体性能时能做出正确而快速判断。
This paper establishes two OFDM communication system model,uses MATLAB language simulation of the whole system and gets the corresponding simulation results.Based on this,it has made more comprehensive and in-depth analysis about the performance of OFMD system on eight kinds of channel models and three kinds of channel estimation.The obtained conclusion help to make a correct and quick judgement on choosing what kind of channel estimation algorithm to improve the whole performance of the communication system in different environment.
