Orthogonal Frequency Division Multiplexing (OFDM) has become a popular modulation method in high speed wireless communications. By partitioning a wideband fading channel into flat narrowband channels, OFDM is able to mitigate the detrimental effects of multipath fading using a simple one-tap equalizer. There is a growing need to quickly transmit information wirelessly and accurately. OFDM is a ...

We propose the progressive rate-filling method as a framework to study agile construction of multilevel polar-coded modulation. show that bit indices within each component polar code can follow fixed, precomputed ranking sequence (e.g., Polar in 5G standard) while their allocated rates (i.e., number information bits code) be fast computed by exploiting target sum-rate approximation and proper m...

Networked haptic virtual environments (NHVEs) are those in which multiple users collaborate and experience force feedback at the same time. The robustness of such systems needs to be tested under various network conditions that closely mirror the Internet. Previously, we had proposed three virtual coupling schemes to maintain position coherency in a NHVE, which were tested using constant and th...

The core objective of transmission tariffs is the recovery costs related to transport electricity. A usual component a tariff fixed charge that covers network infrastructure. As many customers use power grid, rate this should reflect, as closely possible, actual supplying energy individual consumers. These result from which elements have been used in delivering electricity, and what extent thes...

This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....
