Teaching Quadrature Phase Shift Keying (QPSK)

 

Quadrature phase-shift keying (QPSK) is an important digital communications concept commonly used in digital radios and low-power devices. In this video, see how experiential learning allows students to experiment with real-world, over-the-air communication schemes and reinforce modulation concepts such as symbol mapping, upsampling, and pulse shaping.
