This invention relates to MIMO test method in a multi-user MIMO radio communication system including: estimating the channel matrixes of all users at the base station, computing an orthogonal projecting matrix M of the interference matrix of each user and transmitting M to each user periodically, receiving data sent by the base station at the user end and getting the orthogonal projecting matrix M from the received data, transforming the MIMO test of a desired user to the minimum value of a K-element secondary convex function, in which, K expresses the number of sending antennas and getting estimation of the test data by a ball test method.
一种多用户多输入多输出无线通信系统中的MIMO检测方法,包括步骤:在基站估计所有用户的信道矩阵;计算每个用户的干扰用户矩阵的正交投影矩阵M,并将每个用户的正交投影矩阵M定期发送给每个用户;在用户端接收基站发送的数据,并从接收的数据中得到正交投影矩阵M;利用正交投影矩阵M将期望用户的MIMO检测转化为K元二次凸函数的极小值,其中K表示对期望用户而言,发送天线的个数;利用球检测的方法,得到检测数据的估计。

Wavelet multi-scale analysis is applied to the research on lunar gravity field and the explanation of lunar inner structure. In this paper, the nearside of the Moon with higher quality data is chosen as the test area, and free air gravity data from "Clementine" mission are used as original data to decompose gravity of some specific mare basins. With the results of numerical test, we also explain the hierarchical structure of the Moon, analyze the thickness of mare fillings and the Moho topography under mare basins, and verify the results by comparisons.
本文将小波多尺度分析引入月球重力场的研究,选取测量数据质量较好的月球近区作为实验区域,以"Clementine"探测器获得的自由空气重力异常作为原始数据对主要月海盆地进行了局部的重力异常分解,解释了月球内部基本分层结构,并利用主要月海盆地的实验结果分析了月海下部质量异常以及莫霍面的起伏形态,与已有研究成果进行比较证明了方法的适用性及结果的合理性。

For the lack of return data in the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted, and forecasting is carried out by only using a few data. When the data amount reaches 50, the hidden quantitative relationship between sale quantity and return quantity is established by performing the transfer function-noise model. Its parameters are determined through model identification, parameters estimation and diagnostic checking. Then, forecasting return is accomplished.
回收初期数据缺乏,采用改进邻域系生成方法的GM(1,1)模型,实现了少量数据情况下的预测;回收数据累积到50个后,利用传递函数噪声模型构建了回收量和前期销售量之间的内在数量关系式,然后通过模型识别、参数估计、诊断检验确定了关系式的具体参数,进而实现了回收预测。
