sharkattackgame
说明: 是一个Applet程序,要在浏览器中或用appletviewer执行。当Applet运行时,
鲨鱼会在水平方向持续移动,单击相应的按钮会改变鲨鱼的运动方向。游戏的目标是当猎物
经过时,如果鲨鱼也处在该位置并且完全没入水中,则猎物才被捕获。猎物被捕获时会发出
相应的提示音,并且猎物消失。(is an Applet procedures, and in a browser or appletviewer implementation. When the applet runs, sharks in the horizontal direction will be sustained mobile, click on the corresponding button will change the direction of the shark. The goal of the game when the game is through, if the sharks at the position and did not fully submerged, was captured prey. Prey to be arrested will be issued when appropriate tone and prey disappear.)

OFDMSignalDetection-master
说明: 程序实现的主要功能:
OFDM调制识别:研究了基于高阶累量和基于小波变换的OFDM信号和单载波调制信号的识别算法,仿真分析了两种算法在高斯信道和多径瑞利衰落信道下的信号识别性能。
OFDM参数估计:研究了基于Welch算法和AR模型法求解功率谱进而估计信号带宽的算法,对两种算法的估计性能进行了比较;根据OFDM信号的循环平稳性研究了基于循环谱的载频估计算法;根据 OFDM信号的自相关性研究了基于可变延时自相关和固定延时自相关的FFT相结合的算法,估计了OFDM信号的有效数据长度、符号总长度、循环前缀长度和子载波间隔;最后研究了基于带宽和基于过采样估计子载波数目两种算法,并在高斯信道和多径瑞利衰落信道下对以上参数估计算法进行了仿真分析。
其中OFDM_DEMO为整个项目的程序入口,其余均为辅助函数,每一个函数均有参数注释和功能说明。(The main functions of the program are as follows:
OFDM modulation recognition: the recognition algorithms of OFDM signal and single carrier modulation signal based on high-order cumulant and wavelet transform are studied. The signal recognition performance of the two algorithms in Gaussian channel and multi-path Rayleigh fading channel is simulated and analyzed.)

自适应OFDM系统能根据信道估计得到信道的状态信息,自适应地调节发送端传输参数,从而提高系统的性能。其中OFDM是一种多载波调制技术,具有频谱利用率高、抗多径干扰、抗突发噪声差错等优点。
在VLC中引入自适应OFDM技术,可以提升系统的容量,提高传输质量,使系统具有更大灵活性,改善系统性能。在无线光通信领域对该技术的研究已成为个重要的方向。根据现有的研究人员所发表的文献,大多是基于基础性和理论性的研究,对可见光通信技术与自适应OFDM的研究甚少。(The adaptive OFDM system can obtain the channel state information according to the channel estimation, and adaptively adjust the transmission parameters of the transmitter, so as to improve the system performance. Among them, OFDM is a multi carrier modulation technology, which has the advantages of high spectrum utilization, anti multipath interference, anti burst noise, error and so on.
The introduction of adaptive OFDM technology in VLC, can improve the system capacity, improve the quality of transmission, the system has more flexibility, improve the performance of the system. In the field of wireless optical communication, the research of this technology has become an important direction. According to the literature published by existing researchers, most of them are based on basic and theoretical research, and few studies have been done on visible light communication technology and adaptive OFDM.)
