基于NIOS II的LED屏贪食蛇设计，基于NiosII软核处理器和LED点阵显示屏的贪吃蛇游戏内容是：一条蛇在封闭的围墙里，围墙里随机出现一个食物。玩家通过4个按键控制蛇上下左右移动，且蛇只能沿着头运动的轨迹移动。蛇头撞到食物，则食物被吃掉，蛇身体增长一节，同时记1分，又出现食物，等待蛇通过玩家的控制来吃掉，如果蛇头在移动中出界或咬到自己的身体则游戏结束，并且加入了一些附加功能如蛇身加速，选择难度，开关机屏幕画面的优化等一系列功能，使游戏更具可玩性。(NIOS II LED screen Snake design, NiosII based soft-core processor and LED dot matrix display Snake game content is: a snake in a closed fence, the fence was a random food. Players control a snake through 4 keys to move around, and the head of the snake can move along the track movement. Snakeheads hit the food, the food is eaten, the snake grow body section, but remember one point, appeared foods, through the player controls a snake waiting to eat, if snakeheads bite out of bounds or move their bodies in the game end, and added some additional features such as snake acceleration, choose the difficulty to optimize switching machine screen and a series of features that make the game more playable.)

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)
