coded octal phase shift keying (COPSK)

Coded Octal phase Shift Keying

(COPSK) is a special phase shift keying technique that was developed as early as the mid-1980s. With this phase shift keying, eight phases are encoded. The COPSK method is used for the transmission of digitaldata at high data rates

. TheCOPS modulation is used

, among other things, insatellite communication

inconjunction

withTime Division Multiple Access (TDMA) for data rates of 140 Mbit/s

. Compared to quadrature phase shift keying (QPSK),COPS has a coding efficiency that is 3 dB to 5 dB higher,
