Digital Modulation and GMSK A brief introduction to digital modulation schemes is given, showing the logical development of GMSK from simpler schemes.

这是关于扩频的一些基本知识,希望能对大家有帮助.(this is about spreading some basic knowledge, we want to help.)

针对20个已知类别数据，前15个训练样本和带刺的5个样本，通过该程序可识别出待测的样本属于哪一类。(Data for the 20 known types, the first 15 training samples and barbed 5 samples can be identified by the program which type of samples tested.)

控制台调用，采用内部通信机制实施，达到高效、稳定的目的(Console called the internal communication mechanisms implemented to achieve efficient, stable purpose)

说明：  通过matlab五电平调制，实现更优选择的切换(Through five level modulation, better switching can be achieved)

demodulates the FM modulated signal Y at the carrier frequency Fc (Hz). Y and Fc have sample frequency Fs (Hz). FREQDEV is the frequency deviation (Hz) of the modulated signal.

The recursive function H(T) Calculate the Expected number of failures in (0,T], for Weibull distribution Assumption: T s unit is a day, the smallest time unit.
