编写MATLAB的M文件，用该文件对采用包络检测法解调的2ASK系统的抗噪声性能进行1000个符号的蒙特卡罗法仿真，画出误码率与信噪比之间的关系曲线，其中信噪比的取值为r＝0dB,2Db,4Db,6dB……10Db,同时画出误码率与信噪比的理论曲线，其中信噪比的取值为r＝0dB,0.1dB,0.2dB,0.3dB……10Db-The preparation of MATLAB M-file, use the document on the use of envelope detection de

基于MATLAB的2Ask，2Fsk，2Psk波形产生。-Based on the MATLAB 2Ask, 2Fsk the 2Psk waveform.

2ask调制，波形生成，图像生成，波形识别-2ask modulation, waveform generation, image generation, waveform recognition

本文件是2ask仿真代码。振幅键控是利用载波的幅度变化来传递数字信息，而频率和初始相位保持不变。-This document is 2ask simulation code. Amplitude shift keying of the carrier amplitude variation is the use of digital information to transmit, and the frequency and initial phase remains unchanged.

2ask的调制解调，包括相干解调和非相干解调，并有两者的性能分析-2ask modem, including coherent demodulation and non-coherent demodulation, and performance analysis of both
