QPSK MODULATION AND DEMODULATION
This is called pi/4 QPSK constellation diagram of QPSK will show the constellation points lying on both x and y axes means that the QPSK modulated signal will have an in-phase component (I) and also a quadrature component (Q). This is because it has only two basis functions. A QPSK modulator can be implemented as follows.
QPSK vs DP-QPSK | difference between QPSK and DP-QPSK
QPSK modulation | Quadrature Phase Shift Keying modulation Figure-1: QPSK modulation Block Diagram As shown in the figure-1, QPSK modulator maps 2 bits per symbol. As shown input binary data is divided into two streams using S/P converter. One stream is known as in-phase (I) and the other stream is known as quadrature phase (Q).
QPSK modulation & demodulation (Matlab and Python
Jul 06, 2020The timing diagram for BPSK and QPSK modulation is shown in Figure 2. For BPSK modulation the symbol duration for each bit is same as bit duration, but for QPSK the symbol duration is twice the bit duration: . Therefore, if the QPSK symbols were transmitted at same rate as BPSK, it is clear that QPSK sends twice as much data as BPSK does.[PDF]

QPSK QPSK modulator block diagram Standard QPSK With this form of QPSK it looks like we have two equal bit rate BPSK modulators operating in parallel. The two carrier signals are aid to be in phase quadrature since the sine lags the cosine by 90 ECE 5625 Communication Systems I 5-11[PDF]
