...This demodulation method is called differential detection, and this type of modulation method is called differential phase shift keying (DPSK). Compared to other digital modulation methods, PSK has better error rate characteristics among methods with a similar circuit scale, so it is used in many fields, including wireless communications. *Some of the terminology that mentions "differential phase shift keying" is listed below.

…この復調方式を遅延検波といい,また,そのような変調方式をとくに差動位相変調(DPSK。differential phase shift keyingの略)という。PSKは,他のディジタル変調方式と比べると,同程度の回路規模の方式の中では誤り率特性がよいほうであるので,無線通信をはじめとして,多くの方面で使用されている。… ※「differential phase shift keying」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
