EMIRS 利用小微扰法计算二维高斯粗糙面的辐射系数(EMIRS computes the emissivity from 2-D Gaussian dielectric rough surface using small perturbation method (SPM))

In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.

驱动力和制动力是车辆纵向力学特性中重要部分，本程序采用matlab，根据发动机的万有特性曲线和循环工况，绘制出车辆的驱动力和制动力随时间的关系(The driving force and braking force is an important part of the vehicle longitudinal mechanical properties, the program uses matlab, according to the universal characteristic curve of the engine and the driving cycle, to map out the driving force and braking force of the vehicle over time)
