Modulation methods digital communication



In differential phase shift keying the two possible signal sets are orthogonal
The minimum bandwidth required for a binary phase shift keying signal is equal to the bitrate
Non coherent reception of phase shift keying results in more probability of error than that of coherent reception
Quadrature phase shift keying is the digital modulation with lowest bit error probability
Binary phase shift keying and quadrature phase shift keying have same bit error probability
The minimum bandwidth required for binary phase shift keying is equal to bitrate
The adjacent phasors in an 8 psk system different by
