Information on Quadrature Phase Shift Keying (QPSK)

Quadrature phase-shift keying (QPSK) is a form of phase shift keying (PSK) using four phase states, normally 90 degrees apart.


Other topics in our resources on Communications Systems related to Quadrature phase-shift keying include: 
 
  • Differential phase-shift keying (DPSK)
    		•
  • Binary phase shift keying (BPSK)
