matlab实现几种基本的通信仿真技术 (to achieve basic communication matlab simulation of several)

FIR滤波器的MATLAB程序,可用于算法仿真,非常有用.(fir filter matlab program,could be used to develop algorithm,veri useful.)

In this project, we have designed and implemented a method to estimate the dual frequencies in sinusoids immersed in additive white Gaussian noise. The Cramér-Rao lower bound (CRLB) for the signal model and a nonlinear least square frequency estimator are derived. The estimator is evaluated by numerical examples.

计算灰色关联度，可用于多指标的多方案评价，关联度大的为优，小的为劣。(Gray correlation calculations can be used for multi-index multi-program evaluation, excellent correlation for large and small for the poor.)

QPSK软件接收机,对QPSK整个接收过程进行仿真，包括载频捕获、相位跟踪、滤波、判决等。(QPSK software receiver for receiving QPSK whole process simulation, including the carrier frequency acquisition, phase tracking, filtering, and other judgments.)

说明：  采用谱元法计算声传播问题，带matlab代码(spectral method used for wave transmission problems, with matlab code)

说明：  可以将图的颜色在0位置表现为白色，使用方法为multimap函数，注意将范围设为对称，这样就可以将0设为白色(Can map the location of the performance of the color 0 is white, the use of methods for Multimap function, set the scope of attention to symmetry, this can be 0 is set to white)
