这是一个完整的无线通信系统中物理层的仿真程序，通过扩频技术（直接序列扩频）让信号通过高斯，瑞利等信道进行信噪比分析，得出结论-This is a complete wireless communication systems in the physical layer of the simulation program, through the spread-spectrum techniques (Direct Sequence Spread Spectrum) to signal throu

MIMO系统信道估计算法研究 针对LS算法的分析结论所进行的仿真，将根据分析结果，对信噪比的取值、训练序列的长度以及最优训练的选取，分别进行仿真实验。-MIMO systems channel estimation algorithm for the LS algorithm for the analysis of the conclusions of the simulation, the results of the analysis will be based on the signa

matlab编写的常见调制模式(am,fm,bpsk,qpsk,mask,16qam等)自动识别动态链接库，可以直接被vc调用，信噪比为>=10dB,-matlab write common modulation (am, fm, bpsk, qpsk, mask, 16qam, etc.) automatically identify dynamic link library, you can directly vc called signal to noise ratio> =

仿照着《小波去噪中软硬阈值的一种改良折衷法》一文写的程序，对比了软、硬以及软硬阈值折衷法的信噪比及均方根误差。仿真出来之后，原信号的信噪比是负的，不知道为什么？均方根误差的值也比较大，不知何解？信噪比和均方根误差是参照《基于matlab的小波去噪仿真》：吴伟，《信息与电子工程》 一文写的-Modeled on the written procedures of the hard and soft threshold wavelet de-noising an improved compromis
