防雷工程是一项系统工程，要求将外部防雷装置和内部防雷装置统一考虑，着眼于全方位的雷电综合防护，把机房建筑物的防雷、雷电电磁脉冲（LEMP）防护、设备防雷、电源系统防雷、线路防雷、接地系统、保护装置等综合因素考虑在内。任何方面的遗漏带来的危害都是不能(Mine is a systems engineering project, requiring the external and internal lightning protection lightning protection devices to consider a unified, integrated focus on the full range of lightning protection, lightning protection of buildings to the engine room, lightning electromagnetic pulse (LEMP) protection, equipment, anti- Thunder, lightning protection power system, line lightning protection, grounding systems, protective devices and other comprehensive factors into account. Omission of any harm is not)

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.
