GeneralizedMIMO
应用背景In this context, mobile communications may be allowed to be an indispensable commodity by most, and mobile data, video as well as television services are also becoming an essential part of everyday life. With the introduction of the Android operating system and the iPhone, the use of ebook readers such as the iPad, and the success of social networking using Facebook, the demand for cellular data traffic has grown significantly in recent years. Thus, communications on the move has proven to be transformational, and mobile operators struggle to satisfy the data traffic demands in wireless cellular networks,while keeping their costs at minimum to maintain profitability.关键技术The need for power-efficient MIMO-aided cellular networks requires a paradigm shift in the wireless system design. This trend is irreversible and will have a profound impact on both the theory and p

大数据处理利器 提升普通map的性能
修改普通map,提升性能对于c++程序来说 map的使用无处不在。影响程序性能的瓶颈也往往是map的性能。尤其在大数据情况下,以及业务关联紧密而无法实现数据分发和并行处理的情况。map的性能就成了最关键的技术。比如:ip表、mac表,电话号码表、身份证号码表的查询、病毒木马的特征码的云查杀等等。stl库的map采用二分查找,性能最差。Google的哈希map性能和内存目前是最优的,但是有重复碰撞的机率。我在电信行业和信息安全行业里的工作经历发现,目前网络上的哈希算法都在查询速度上远远无法满足日趋增长的网络大数据要求。因此产生了自己写算法的想法。现在我把自己的算法发布出来。大家可以测试对比发现,我的算法属于零碰撞的几率,但是性能比哈希算法还优。声明:该代码不能用于商业用途,只能用于科学研究。
