Abstract: This paper reports on the first microwave acoustic quadrature phase-shift keying (QPSK) modulator. Phase modulation is achieved via acoustic phase inversion (API) through electric field ...
Abstract: In this letter, an odd-order superposed modulation scheme is studied in non-orthogonal multiple access (NOMA) system. Firstly, we design a novel superposed 32-quadrature amplitude modulation ...
