| 中文摘要: |
| 文章介绍了多进制数字调制中的相位解调。文中在多进制数字相位调制系统模型基础上,引入了M进制相位调制信号的表达式,在多进制数字相位解调中分别对四相绝对相移键控和四相相对相移键控进行了详细地分析。并对四相绝对相移键控的解调采用与2PSK信号类似的方法进行解调,四相相对相移键控的解调分有相干解调和延迟解调两种分别进行了较详细地分析。 |

| The M-ary phase demodulation and detection were analyzed in this paper.The signal expressions of M-ary phase modulation were introduced based on the multi-band digital phase modulation system model.In the multi-band digital phase modulation,the four phase absolute phase shift keying and the four phase relative phase shift keying were respectively analysed in detail.Finally,the four phase absolute phase shift keying was demodulated in a similar method of the 2PSK signal,while the four phase relative phase sh... |
