说明： In this paper, a new direction-of-arrival (DOA) estimation method based on multiple Toeplitz matrices reconstruction is proposed for coherent narrow band signals with a uniform linear array (ULA).(Even in the case of a low signal-to-noise ratio and low snapshot number with half the array aperture reduced, the new method provides good performance on estimation and resolution.)

BER
这是一个matlab和optisystem联合调试用的误码率计算程序，里面的文件报过一个可以用optisystem7和optisystem13可以打开的OSD仿真图，还有一个MATLAB计算BER的程序。给出了如何设置系统的大纲。从OptiSystem的电信号输入到Matlab组件。当OptiSystem运行时，它将调用Matlab组件中的M文件，处理数据，然后将所得的电信号导出回OptiSystem。然后将输出信号连接到BER分析仪。经过我调试，文件齐全，放心下载(The attached image gives an outline of how the system should be setup. You should start with inputting the electrical signal from OptiSystem into a Matlab component. When OptiSystem runs, it will call the M-file in the Matlab component, process the data, and then export the resulting electrical signal back into OptiSystem.The output signal is then connected to the BER Analyzer.)

说明： 2. 关于无线信道的多普勒谱，请回答以下问题：
(1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因；
(2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理；
(3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。
(On the wireless channel of the Doppler spectrum, please answer the following questions: (1) In some radio channels, the Doppler frequency shift will cause the output signal of the wireless channel aliasing. Please describe the aliasing produced a variety of reasons (2) wireless channel in the Doppler spectrum has a classical spectrum (classic spectrum), please explain the mechanism of produce such spectral shape (3), please use the Simulink tool to write code ( S-Function mode), resulting in a single-path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h. And requested the answer: that they used computer-generated classical spectrum is the right possible way.)
