“…In Hammouda's [9], an energy-detection-based transmission scheme is proposed in the Rice channel, and the SEP of the system is derived by approximating the received signal energy as a Gaussian variable, and an iterative algorithm is proposed to design the optimal constellation to improve the reliability of the system. In Han's [10], a constellation design framework for noncoherent massive SIMO systems over correlated channels is developed, which adopted the max-min KL divergence as the objective function to optimize energy-based noncoherent constellations.…”

In this paper, an energy detection-based transmission scheme is proposed to consider a massive single-input multipleoutput (SIMO) system with imperfect channel status information (CSI), where a pulse amplitude modulation (PAM) constellation is used at the transmitter and energy detection is used at the receiver. First, the symbol error probability (SEP) of the system is obtained by theoretical derivation, then the PAM constellation is optimized based on the minimum SEP criterion. The conditions that a suboptimal PAM constellation should satisfy are obtained by relaxing the upper bound of the SEP, and a simple iterative algorithm is proposed to complete the constellation design accordingly. The simulation results show that the PAM constellation designed can effectively improve the reliability and reduce the SEP.
