WebbOﬀset quadrature phase-shift keying (OQPSK) is a constant-envelope modulation that has no 180-deg phase shifts and, therefore, has a much higher spectral containment than … Webb8 juni 2008 · The basic form of phase shift keying is known as Binary Phase Shift Keying (BPSK) or, occasionally, Phase Reversal Keying (PRK). A digital signal alternating between +1 and 1 (or 1 and 0) will create phase reversals – i.e. 180° phase shifts – as the data shifts state (Figure 3-14). Figure 3-14. Binary phase shift keying. open houses in ct todaySometimes 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 … iowa state us diversity requirement
