Generation of ASK:
Amplitude shift keying - ASK - in the context of digital communication is a modulation process which imparts to a sinusoid two or more discrete amplitude levels 1. These are related to the number of levels adopted by the digital message. For a binary message sequence, there are two levels one of which is typically zero. Thus the modulated waveform consists of bursts of a sinusoid.
Demodulation of ASK:
ASK signal has a well defined envelope. Thus it is amenable to demodulation by an envelope detector. Some sort of decision-making circuitry is necessary for detecting the message. The signal, which is a binary sequence is recovered by using a correlator and decision making circuitry.

Couplafunction
Copula函数描述的是变量间的相关性，实际上是一类将联合分布函数与它们各自的边缘分布函数连接在一起的函数，因此也有人将它称为连接函数。本程序已调试，可以运行。(Copula function describes the correlation between variables, in fact, is a class of joint distribution functions and their respective edge distribution functions connected together, so it is also called the connection function. This procedure has been debugging, you can run.)
