</html><description>Description: QPSK (Quadrature Phase Shift Keying) modulation is a digital modulation technique that transmits data by varying the phase of a carrier signal. Instead of using only two phases as in BPSK (Binary Phase Shift Keying), QPSK employs four distinct phases, allowing two bits of information to be encoded per symbol. This translates to greater [&hellip;]</description></oembed>
