WebApr 11, 2024 · QPSK (Quadrature Phase Shift Keying) is type of phase shift keying. Unlike BPSK which is a DSBCS modulation scheme with digital information for the message, QPSK is also a DSBCS modulation scheme but it sends two bits of digital information a time (without the use of another carrier frequency). 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 … WebMinimum Shift Keying (MSK) • MSK is a continuous phase FSK (CPFSK) where the frequency changes occur at the carrier zero crossings. 1.The difference between the frequencies is always 1⁄2 of the data rate. 2.– This is the minimum frequency spacing that allows 2 FSK signals to be coherently orthogonal. correct way to hold badminton racket
