The first helps you pack, you have a lot of advantages, cannot mirror on your photograph come out, you speak what give to the other side directly, feel embarrassed expression comes out, undertake conduct propaganda to you by our soubrette website, achieve your desire, the 2nd problem, have a problem e.g. you bad to ask, e.g. settle on of a girl a boy, this kind of problem, have oneself advocate house, this kind of problem is bad at the beginning to ask, through our website side you ask, after bilateral appointment was over, do not know the other side normally how, main service is a phone the service basically is this respect, our group is the white-collar that comes 45 years old in 25 years old, the time that the mainest is them is exceedingly valuable, our service is aimed at the service that reflected at 2 o'clock was to reflect two problems, the first is the time that saved them, make them not beautiful many time, spend several hours to enter these activities, if if your disposition compares undemonstrative word, only 3 two people undertake inquiring to you, if we serve with soubrette website, have man-to-man service, improve your efficiency that match, we everyday add a member newly to 20 thousand increase a membership newly, the growth rate of our income is very rapid, we are the first soubrette websites, we cannot say specific number now, we everyday income is us the summation that 3 the biggest competitors add up is even tall, we and other websites still do not have gain euqally, the growth rate of our income is very rapid, we can become the website of the first gain of Chinese.

第一个帮你包装，您有很多的优点，你的照片上不能反映出来的，您直接给对方讲出的话，不好意思表达出来，由我们的红娘网站对您进行宣传，达到你的愿望，第二个问题，比如说你有一个问题不好问，比如说一个女孩子看上了一个男孩子，这种问题，有自己的主屋，这种问题一开始不好问，通过我们的网站帮您打听，双方约会完了以后，通常不知道对方怎么，主要的服务是电话服务主要是这方面，我们的群体是在25岁至45岁的白领，最主要的是他们的时间非常的宝贵，我们的服务针对两点体现的服务是体现了两个问题，第一个是节省了他们的时间，使得他们不要花大量的时间，花好几个小时参加这些活动，如果你性格如果比较腼腆的话，只有两三个人对你进行打听，我们用红娘网站服务的话，进行一对一的服务，提高你的匹配的效率，我们每天的新增会员有两万新增会员，我们的收入的增长速度非常快，我们是第一个的红娘网站的，现在我们不能讲具体的数字，我们每天的收入是我们三家最大的竞争对手加起来的总和还要高，我们和其他的互联网站一样还没有盈利，我们的收入的增长速度很快，我们会成为中国第一家盈利的互联网站。

By utilizing the unitary matrix, the transmitter decouples the input signal into spatial orthogonal beam directions with the matched filters in beam directions in the receiver, and the gain obtained by each data block can be equivalent to the sum of the projection from the channel matrix to the corresponding beam directions. Beam selection is adopted to maximize the minimum gains of all the blocks, which can improve the system diversity gain efficiently.

发射端采用酉矩阵将数据映射到空间正交的波束方向上，通过接收端波束方向上的匹配滤波，各数据分块所获得的增益为信道矩阵在其波束方向上的投影之和，波束选择通过最大化所有数据分块最小增益，从而有效地提高了系统的分集增益。

Cotton is ursine: We basically not be to rely on to do a website to come of gain, we are business of network base service, that is to say we are to rely on to network user to offer a few if the domain name is registered, fictitious lead plane ah still have a server mandatory come this piece of gain.

棉花熊：我们呢主要不是靠做网站来盈利的，我们是网络基础服务商，也就是说我们是靠给网络用户提供一些如域名注册、虚拟主机啊还有服务器托管这块来盈利的。
