To avoid the modal crosstalk-induced power fading, a mode assignment technique has been proposed and experimentally demonstrated for mode division multiplexed W-band radio-over-fiber links.
A closed-form capacity expression for polarization-multiplexed coherent MIMO radio-over-fiber (RoF) links at millimeter-wave bands is derived and the impact of the fiber's polarization rotation and the wireless antenna misalignment on the MIMO channel capacity is revealed. The analytical results are validated via an indoor W-band (75–110 GHz) 10-Gbaud MIMO-RoF transmission experiment.
20Gb/s seamless 2×2 MIMO transmission of W-Band millimeter-wave signals over a 30-km modal-dispersion-compensated mode-division multiplexed link and a 2.5-m wireless path, is demonstrated for enhancing the transmission capacity in radio-over-fiber systems.
An inductive-coupling programmable bus for NAND flash memory access in solid state drive (SSD) is presented. Compared to the conventional SSD, this wireless interface using relayed transmission reduces power consumption to 1/2, I/O circuit-layout area to 1/40, and achieves a data rate of 2 Gb/s in 0.18 ??m CMOS process. In addition, since this wireless interface enables one package to contain 64 chips,...
The cost for screening test on wafer has continually increased each year; the test cost especially for low-price IC chips, for example, exceeds one-third of total chip cost. Furthermore, screening test on wafer to select good dies (Known- Good-Die) will become more significant to improve the yields of up-to-date packages such as Chip-on-Chip and 3D-LSI. Therefore, the cost reduction for screening...
A wireless communication technique, which enables a controller chip to communicate with random access with a stack underneath it of 64 NAND flash memory chips at a data rate of 2 Gb/s using relayed transmission is developed. This technique can be applied to memory access in solid-state drives (SSD). The wireless interface allows the removal of a highly capacitive ESD protection device and results...
