In this paper, we present a novel data-based method for simultaneous Maximum Likelihood (ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision multiplexing (OFDM) systems. Statistical properties introduced by the cyclic pre痻, a guard space between OFDM symbols, provide su眂ient information about the unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻 allows the estimation to be performed without additional pilots. Simulations show that the performance of the frequency estimator is applicable in a tracking mode while the timing estimation can be used in an acquisition mode.

周期图法谱估计需要对信号序列“截断”或加窗处理，其结果是使估计功率谱密度为信号序列真实谱和窗谱的卷积，导致误差的产生。本程序分别设计了周期图法,最大熵功率谱估计和Welch法以及它们的对比,最大熵功率谱估计目的是最大限度地保留截断后丢失的“窗口”以外信号的信息，使估计谱的熵最大。(Periodogram spectrum estimation signal sequence needs to " cut off" or add the window handle, the result is an estimated power spectral density of the signal sequence of the real spectrum and spectral convolution window, resulting in the generation of errors. The procedures were designed periodogram, maximum entropy power spectrum estimation and the Welch method and their comparison, the maximum entropy power spectrum estimation purpose is to maximize the retention of truncated after the loss of the " window" than the information signal, the entropy of the estimated spectrum maximum.)

DUNE (Distributed and Unified Numerics Environment)，分布和统一数值解环境，是一种求解偏微分方程的基于网格的方法（PDE）的模块化的工具箱。DUNE是所有这些体现了科学计算的概念从抽象的接口设置第一次。现代C + +编程技术使同样的概念非常不同的实现使用一个非常低的开销一个共同的接口。因此，DUNE确保在科学计算的效率，并支持高性能计算应用。(DUNE (Distributed and Unified Numerics Environment), distribution and unified numerical solution of the environment, is a solution of partial differential equations of the grid-based methods (PDE) of the modular toolbox. DUNE is that all these reflect the concept of scientific computing from the abstract interface settings for the first time. Modern C++ programming techniques to the same concept is very different implementations use a very low cost of a common interface. Therefore, DUNE ensure the efficiency of scientific computing, and supports high-performance computing applications.)
