NSE_QNS

this is Matlab Circular convolution file name is circonv.m

this is file that how you can encode cyclic code

说明：  非常实用的Matlab程序，对Matlab程序的学习很有帮助。(Matlab programs are very useful for learning Matlab program helpful.)

对于参数估计问题,克拉美罗界(简称CRB)为任何无偏估计量的方差确定了一个下限. 即不可能求得方差小于下限的无偏估计量,并为比较无偏估计量的性能提供了一个标准. 本程序对CLRB（克拉美罗下界）进行了描述，预留了参数。 希望能对同志们提供帮助。(For the parameter estimation problem, Cramer-Rao bound (referred to as CRB) for any unbiased estimator of variance to determine a lower limit that can not be obtained is less than the minimum variance unbiased estimator and unbiased estimator for comparing the performance of provides a standard procedure for this CLRB (Cramer-Rao lower bound) for a description of the reserved parameters. Hoping to help comrades.)

it is about binary phase shift keying

freeman_2components_decomposition_T3 效果不错(freeman_2components_decomposition_T3 have a good result)

Connection system (QAM, PA, AWGN). Demodulation with BER computing.

多普勒信号模型，多普勒信号快速傅立叶法分析频谱，FFT(Doppler signal model, the fast Fourier analysis of Doppler signal spectrum, the FFT)

利用遗传算法求解8数码问题。这里是个框架性的，可以有很多改进之处(Using Genetic Algorithm eight digital problem. Here is a framework, there can be a lot of improvements at)
