MODULATION DIGITAL AND ANALOG

用于变电所的电力103通信测试的源代码,主要用在工控行业(103 for electricity substation communications test source code, mainly used in the industrial sector)

a reference book about stability of time delay systems

说明：  通过labview实现通信信道仿真中的信道估计以及时域均衡，注意这个是以及完整实现了信道的搭建，通过添加时域均衡以及信道估计实现最终的仿真(The channel estimation and time-domain equalization in communication channel simulation are realized by labview. Note that this is to build the channel completely. The final simulation is achieved by adding time-domain equalization and channel estimation.)

本文分析了多级维纳滤波器的特性，在加性噪声和二维天线阵列如均匀圆阵、均匀面阵、十字阵等条件和背景下，对信源个数和信源参数估计问题进行了研究，提出了基于多级维纳滤波器前向分解特性的快速参数估计方法，同时提出了基于多级维纳滤波器的二维ESPRIT参数估计方法，该类方法无需协方差矩阵的估计运算及分解运算，计算复杂度较低。另外，还提出了对信源个数的估计算法。(This paper analyzes the characteristics of multistage Wiener filter, in the additive noise and the two-dimensional antenna array such as a uniform circular array, the uniform array, cross array conditions and background, the source number and source parameter estimation problem undertook study, put forward based on Multistage Wiener filter prior to the decomposition characteristics of fast parameter estimation method, at the same time based on Multistage Wiener filter 2D ESPRIT parameter estimation method, the method does not need to estimate of covariance matrix calculation and decomposition, relatively low computational complexity. In addition, also put forward for source number estimation algorithm.)

说明：  Python异步IO模块源代码，众所周知Python由于全局锁的问题在多线程支持上存在弊病，通过异步可有效提升效率(Python asynchronous IO source code)

说明：  分别用M序列gold序列正交gold序列设计直接序列扩频通信系统并分析误码率(Using m-sequence gold sequence orthogonal gold sequence to design DSSS communication system and analyze the bit error rate)

说明：  broadcom公司芯片驱动接口命令行操作指导(Broadocom chip driver operation command line interface instructions)
