Abstract:
Recent wireless communication systems strongly require modulation scheme with higher spectral efficiency. In this paper, we propose a new modulation scheme, i.e., the Quadrature Single Side Band (Q-SSB) modulation scheme, which orthogonally multiplexes two SSB signals and it has twice spectral efficiency. Under AWGN channel environment, the Bit Error Rate (BER) performance of the QPSK based Q-SSB signal, i.e., two independent Amplitude-Shift Keying SSB (ASK-SSB) signals, is superior by 3.5dB in CNR in comparison to the same data rate and the same occupied bandwidth of 16QAM signal. A key idea of our Q-SSB modulation scheme is to introduce a power-domain multiplexing type of Non-Orthogonal Multiple Access (NOMA) technique for removing the Hilbert transform terms from in-phase and quadrature components in the receiver side.
