- : 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。

- 频域不同导频密度的信道估计在被研究,并且在高低时延信道其信道估计被固定了导频分配时域。频域信道估计是基于插补,多项式的广义线性模型(或最小二乘法)和维纳滤波(或线性最小均方误差法)的方法。时域的信道估计是用线性插补完成的。我们通过测量在基于克拉克散射模型的瑞利衰落信道上并带有QPSK调制的粗误码率,已经比较了所有这些方案的结果。-Different pilot density in frequency domain channel estimate to research, and its hi
