本论文以OFDM系统为基础,介绍了OFDM系统的基本原理,以及使用OFDM技术的优势所在,并且展望了今后的无线移动技术的发展前景。在简单介绍OFDM原理的同时,着重阐述了OFDM系统在不同信道环境和不不同实现方式下的误码性能。主要包括了OFDM系统在加性白高斯信道,在加性白高斯信道和多径干扰两种不同信道环境下系统的误码性能,其中后者还研究了系统在有保护间隔与无保护间隔的误码性能比较。在理论分析的基础
(This thesis is based on the OFDM system, the basic principle of the OFDM system, as well as the advantages of using OFDM technology, and future prospects for the development of future wireless and mobile technologies. OFDM principle in brief, focusing on the BER performance of OFDM systems under different channel conditions and different implementations. Including OFDM system in additive white Gaussian channel, additive white Gaussian channel and multipath interference of two different channel environment, the system BER performance, the latter of which also studied the system in a protected interval without guard interval BER performance comparison. The basis of theoretical analysis)

bobing
设计主要分两部分:博饼功能的实现和图形界面的生成。主要设计两个类,一个是Dice,记录骰子值,根据骰子值在指定位置绘制骰子。另一个类是Game,主要实现大致框体的绘制和博饼功能的实现。博饼功能主要用到伪随机函数。主函数用到两个线程,用来处理后台输入和骰子的循环输出。(Design main is divided into two parts: bo bread and the realization of the function of the generation of graphical interface. The main design two classes, one is the Dice, record the Dice value, according to the Dice in the location specified value draw Dice. Another kind is Game, mainly realizes the drawing of body roughly box beau and the realization of the function of bread. Bo bread function mainly use pseudo-random function. The main () function use two thread, used to deal with the background of the dice input and output cycle.
