摘要
在无线通信系统中,存在着严重的频率选择性衰落、快衰落和慢衰落,以及各种噪声的干扰和多径传播下的码间串扰等问题,这些问题都会严重地影响着通信系统的性能和质量。为了解决这些问题,本文对基于FFT算法的OFDM系统信道进行了系统仿真及性能分析。仿真结果表明,本算法具有性能好、复杂度低的优点。
In wireless communication systems, there is a serious frequency selective fading, fast and slow fading, as well as a variety of noise interference and multipath spread of Interference between the codes. These problems will seriously affect the communication system performance and quality, In order to solve the problems, system simulation and performance analysis on the FFT algorithm based on the OFDM channel system have been done in this paper. According to the simulation results , this method has good performance and low complexity.
