Abstract: New, compact multimode interference couplers with tunable power splitting ratios have been realized. Experiments show large tuning ranges. Such couplers are needed to optimize ON-OFF ratios ...

The U.S. president can seem like a “chairman of the board,” atop a massive bureaucracy that often runs itself. But the Trump ...

Abstract: In this paper, we apply fountain codes to control the peak-to-average power ratio (PAPR) of orthogonal frequency-division multiplexing (OFDM) signals. The main key idea of the proposed ...
