modulation – Why does NB-IoT use standard QPSK in multi-tone transmission, when pi/4 QPSK is implemented for single-tone?

I’ve been studying the modulation schemes used in NB-IoT communication, with a particular focus on energy efficiency. I’ve noticed that QPSK (Quadrature Phase Shift Keying) is used in multi-tone transmission,…Read moremodulation – Why does NB-IoT use standard QPSK in multi-tone transmission, when pi/4 QPSK is implemented for single-tone?
