Sometimes this is known as quadriphase PSK, 4-PSK, or 4-QAM. (Although the root concepts of QPSK and 4-QAM are different, the resulting modulated radio waves are exactly the same.) QPSK uses four points on the constellation diagram, equispaced around a circle. With four phases, QPSK can encode two bits per symbol, shown in the diagram with Gray coding to minimize the bit error … Webbthe adoption of two interoperable waveforms known as Feher-patented quadrature phase shift keying (FQPSK) and shaped offset quadrature phase shift keying (SOQPSK).
