This paper proposes overloaded multiuser multiple-input-multiple-output (MU-MIMO) that is able to increase network throughput by increasing the number of the signal streams to more than that of receive antennas. The spatial filter is employed at each user for such spatial multiplexing. In addition, the proposed overloaded MU-MIMO applies the non-linear precoding with the lattice reduction for impr...Show More
This letter reports the successful demonstration of large-current and high-voltage (001) vertical-type two-dimensional hole gas (2DHG) diamond trench metal-oxide-semiconductor field-effect transistors (MOSFETs) with a p−-drift layer. The fabricated transistor demonstrated a maximum drain current density of 210 mA/mm, a field-effect-mobility of 61 cm2V−1s−1, and a specific on-resistance of 23 $\te...Show More
Diamonds are highly favored materials in high-temperature and high-power operations owing to their excellent characteristics, and diamond p-channel field-effect transistors (p-FETs) considerably aid in the improvement of CMOS technology, providing high performance, which is essential for inverter operations. This study demonstrates a low ON-resistance (001) vertical-type two-dimensional hole gas (...Show More
