Quadrature Spatial Scattering Modulation for mmWave Transmission

In this letter, we investigate a novel quadrature spatial scattering modulation (QSSM) transmission technique based on millimeter wave (mmWave) systems, in which the transmitter generates two orthogonal beams targeting candidate scatterers in the channel to carry the real and imaginary parts of the conventional signal, respectively. Meanwhile, the maximum likelihood (ML) detector is adopted at the receiver to recover the received beams and signals. Based on the ML detector, we derive the closed-form average bit error probability (ABEP) expression of the QSSM scheme. Furthermore, we evaluate the asymptotic ABEP expression of the proposed scheme. Monte Carlo simulations verify the exactness and tightness of the derivation results. It is shown that the ABEP performance of QSSM is better than that of traditional spatial scattering modulation.

Automated summary

In this study, a novel quadrature spatial scattering modulation (QSSM) transmission technique based on millimeter wave systems is investigated. The transmitter generates two orthogonal beams to target candidate scatterers in the channel and carry the real and imaginary parts of the conventional signal. The maximum likelihood (ML) detector is used at the receiver to recover the received beams and signals. The closed-form average bit error probability (ABEP) expression and asymptotic ABEP expression of the QSSM scheme are derived and verified through Monte Carlo simulations, demonstrating its improved performance compared to traditional spatial scattering modulation.
