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.

The use of fingerprints for identification has been
employed in law enforcement for about a century. A much
broader application of fingerprints is for personal
authentication, for instance to access a computer, a network, a
bank-machine, a car, or a home. The topic of this chapter is
fingerprint verification, where "verification" implies a user
matching a fingerprint against a single fingerprint associated
with the identity that the user claims. The following topics are
covered: history, image processing methods, enrollment and
verification procedures, system security considerations,
recognition rate statistics, fingerprint capture devices,
combination with other biometrics, and the future of fingerprint
verification.

说明： Matlab是Matlab产品家族的基础，它提供了基本的数学算法，例如矩阵运算、数值分析算法，Matlab集成了 2D和3D图形功能，以完成相应数值可视化的工作，并且提供了一种交互式的高级编程语言——M语言，利用M语言可以通过编写脚本或者函数文件实现用户自己的算法。
这是关于matlab的教程(Matlab family of products is the basis of Matlab, which provides the basic mathematical algorithms, such as matrix computation, numerical analysis algorithms, Matlab integrates 2D and 3D graphics features, in order to complete the corresponding numerical visualization work, and provides an interactive high-level programming languages- M language, the use of M language can function through the preparation of the script or document to achieve the user)
