通信原理仿真 码型反变换的仿真实现 Ⅰ、基本任务：由抽样判决后的AMI码型和CMI码型数字序列恢复出原始的PCM脉冲编码信号。 主要步骤和要求： （1）由抽样判决后的AMI码型数字序列恢复出原始的PCM脉冲编码信号（0、1信号）。要求抽样判决后的AMI码型数字序列可以是数字型也可以是字符型；要求画出码型反变换前后的波形图。 （2）由抽样判决后的CMI码型数字序列恢复出原始的PCM脉冲编码信号。要求抽样判决后的CMI码型数字序列可以是数字型也可以是字符型；要求画出码型反变换前后的波形图。 Ⅱ、选做任务：由抽样判决后的HDB3码型数字序列恢复出原始的PCM脉冲编码信号。 主要步骤和要求： 由抽样判决后的HDB3码型数字序列恢复出原始的PCM脉冲编码信号（0、1信号）。要求抽样判决后的HDB3码型数字序列可以是数字型也可以是字符型；要求画出码型反变换前后的波形图。 (Communication theory simulation Fifth problem, Pattern Simulation of inverse transform Ⅰ, basic tasks: decision by the sampling pattern after AMI and CMI pattern sequence to recover the original digital PCM pulse code signal. Main steps and requirements: (1) post-judgment by the AMI code sample digital sequence to restore the original PCM pulse code signal (signal 0,1). AMI requires post-judgment sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform. (2) post-judgment by the CMI sampling digital code sequence to restore the original PCM pulse code signal. Requirements of post-judgment CMI sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform. Ⅱ, choose to do the task: the post-judgment by the sample type HDB3 code sequence to recover the original digital PCM pulse code signal. Main steps and requirements: Pos)
