noun
differential phase-shift keying; DPSK
Technical term in digital communications; a modulation method where the phase of the carrier signal is changed relative to the previous symbol.
差動位相偏移変調は、無線通信でよく使われる変調方式の一つです。
Differential phase-shift keying is one of the modulation methods often used in wireless communication.
Phase-shift keying (PSK) without the differential aspect; 差動位相偏移変調 adds differential encoding to improve robustness against phase ambiguity.
Compound of 差動 (differential), 位相 (phase), 偏移 (shift), and 変調 (modulation), directly calqued from English 'differential phase-shift keying'.
