应用背景This paper considers the problem of interference mitigation in multi-cell multi-antenna time division duplex (TDD) wireless systems for downlink transmission. An efficient way to obtain channel state information (CSI) at the base station is by using uplink pilots and reciprocity of the downlink channel. At the same time, it has been shown that pilots from different cells contaminate each other, resulting in corruption of precoding matrices used by base stations, and high inter-cell interference. This paper studies the effects of shifting the location of pilots in time frames used in neighboring cells, and its effectiveness in obtaining better channel estimates, and, thereby, inter-cell interference reduction.关键技术Wireless cellular network designs with multiple antennas have been adopted by several modern wireless systems, which aim for high throughput as well as high

数据挖掘中的一种方法,可以用来对一组数据进行频繁项集的挖掘。是一种很好的算法，同时，也存在一些不足，需要加以改进！-a kind of arithmetic in datamining

计算方法经典算法(弦截法二分法牛顿迭代法龙贝格算法)-classic calculation algorithm (xianjie Act dichotomy Newton Romberg algorithm)

这个程序做了一个gauss-jordan算法，首先你需要介绍你要用多少个表达式，然后你介绍每一个表达式的系数，然后程序给你一个gauss-jordan过程的数组，在计算方法时，可以观察不同的过程。最后，你可以看到真正的解决方案，如果你有3个ecuations，你将有a，b和c。这个程序不会验证当你介绍一个字母。
