On the Capacity of Generalized Quadrature Spatial Modulation
Kein Yukiyoshi, Naoki Ishikawa
In this letter, the average mutual information (AMI) of generalized quadrature spatial modulation (GQSM) is first derived for continuous-input continuous-output channels. Our mathe…
Accelerating Grover Adaptive Search: Qubit and Gate Count Reduction Strategies with Higher-Order Formulations
Yuki Sano, Kosuke Mitarai, Naoki Yamamoto +1
Grover adaptive search (GAS) is a quantum exhaustive search algorithm designed to solve binary optimization problems. In this paper, we propose higher-order binary formulations tha…
Optimal but Low-Complexity Optimization Method for Nonsquare Differential Massive MIMO
Yuma Katsuki, Naoki Ishikawa
In this paper, we propose an optimal but low-complexity optimization method for nonsquare differential massive MIMO. While a discrete nonlinear optimization is required for the con…
A New Noncoherent Gaussian Signaling Scheme for Low Probability of Detection Communications
Yuma Katsuki, Giuseppe Thadeu Freitas de Abreu, Koji Ishibashi +1
We propose a novel, Gaussian signaling mechanism for low probability of detection (LPD) communication systems with either single or multiple antennas. The new scheme is designed to…
