Description: On the Energy Detection of Unknown Signals Over Fading ChannelsAbstract—This letter addresses the problem of energy detection of an unknown signal over a multipath channel. It starts with the no-diversity case, and presents some alternative closed-form expressions for the probability of detection to those recently reported in the literature. Detection capability is boosted by implementing both square-law combining and square-law selection diversity schemes. Index Terms—Diversity schemes, energy detection, fading channels, low-power applications, square-law detector, unknown signal detection.

Description: 郭涛算法(GuoA)是基于子空间搜索(多父体重组)和群体爬山法相结合的演化算法。它通过利用少数个体所张成的子空间随机生成新的个体,体现了随机搜索的非凸性。此外,由于GuoA算法采用了单个体劣汰策略,算法在每次演化
迭代中,只把群体中适应性能最差的个体淘汰出局,淘汰压力
较小,既保证了群体的多样性,又可使具有较好适应性的个体能够一直保留。实践证明, GuoA算法具有较好的坚韧性,对于不同的优化问题无须修改算法的参数,而且效率很高,可能同时找到多个最优解。-Guo Tao algorithm (GuoA) is based on the sub-space search (more than the reorganization of the parent body) and combination groups climbing the evolutionary algorithm. It is through the use of a small number of individual sub-space by Zhang generate a new random individual, reflects the random search of the non-convexity. In addition, the algorithm uses a single GuoA poor individual survival strategies, the evolution algorithm in each iteration, only to groups of individuals to adapt to the worst performance out of the game, out less stressful, not only to ensure the diversity of the groups, but also could have better adaptability to the individual has been retained. Practice has proved that, GuoA algorithm has good tenacity, and for different optimization algorithm is no need to change the parameters, and efficient, you may find more than one optimal solution at the same time.

Description: 新闻发布系统(News Release System or Content Management System)又叫做内容管理系统,是一个基于新闻和内容管理的全站管理系统,新闻发布系统是基于B/S模式的WEBMIS系统,本系统可以将杂乱无章的信息(包括文字,图片和影音)经过组织,合理有序地呈现在大家面前.当今社会是一个信息化的社会,新闻作为信息的一部分有着信息量大,类别繁多,形式多样的特点,新闻发布系统的概念就此提出.新闻发布系统的提出使电视不再是唯一的新闻媒体,从此以后网络也充当了一个重要的新闻媒介的功能.简单地说,新闻发布系统就是充当一个网络新闻媒介的功能,主要实现对新闻的分类,上传,审核,发布,模拟了一般新闻媒介的新闻发布的过程,通过不同权限的账号分别实现以上所说功能,当然这些功能也可以是某一个账号全部具有.-News Publishing System (News Release System or Content Management System) also known as content management systems, is a news and content management based on the entire station management system, news publishing system is based on B/S mode WEBMIS system, the system can be chaotic information (including text, pictures and video) is organized, rational and orderly presentation in front of everyone. today s society is a society of information, news as part of the information has a large amount of information, of the variety, diversity of features, press releases The concept thereon. press releases made the system so that TV is no longer the only news media, then on the network also acts as an important function of the media. In short, news release system is to act as a network media function, mainly to achieve the classification of news, upload, review, publish, simulate the general process of news media, through different permissions to achieve the above mentioned account Fenbie function

Description: In March 2006 an IEEE task group was created to for incorporating mobile multihop relay capabilities in the mobile Wimax standard IEEE 802.16e. This group came up with an amendment to the 16e standard which is called 802.16j. This amendment is fully backward compatible. The addition of relay capability does not affect the design of MS unless MS has to exploit some optional features such as receive diversity. The BS needs to change slightly and is called MR-BS to differentiate it from BS with no MMR capabilities.

Description: The receiver performance is quantified by depicting the receiver operating char- acteristics (ROC) curves. This curves serve as a tool to and study the performance of a sensing scheme. ROC graphs are employed to show trade-of vs between detection probability and false alarm rates, (i.e. PD versus PFA), thus allowing the determination of an optimal threshold. To illustrate the performance of energy detectors, we generate complementary ROC curves (the average probability of miss detection $ P_{md} 1 - P_d$ versus the false alarm probability $P_f$ for different receiver structures and in different fading environments.Fig. 1 illustrates the complementary ROC curves for a single channel reception (no diversity) over AWGN channels. This figure depicts the complementary ROC curves for energy detectors.
