: 正交频分复用( O F D M) 是第四代移动通信的核心技术。 该文首先简要介绍了O F D M基本原理, 重点研究了理想同步情
况下, 保护时隙( c P )和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对O F D M系统性能的影响。 在给出O F DM系
统模型的基础上, 用 MAT L A B语言实现了整个系统的计算机仿真并给出参考设计程序。 最后给出在不同的信道条件下, 保
护时隙、 信道估计方法对 OF DM系统误码率影响的比较曲线, 得出了较理想的结论。

灰太狼优化算法
说明: GWO算法模拟了灰狼在自然界中的领导层次和狩猎机制。四种类型的灰狼,如alpha,beta,delta和omega,用于模拟领导层次结构。此外,实施狩猎,搜寻猎物,环绕猎物和攻击猎物的三个主要步骤以执行优化。
压缩包包括:发表的论文、优化算法代码、优化工具箱。(The GWO algorithm mimics the leadership hierarchy and hunting mechanism of grey wolves in nature. Four types of grey wolves such as alpha, beta, delta, and omega are employed for simulating the leadership hierarchy. In addition, three main steps of hunting, searching for prey, encircling prey, and attacking prey, are implemented to perform optimization.
Compression packages include: published papers, optimization algorithm code, optimization toolbox.)
