— In this paper, we investigate resource allocation for a multi-user OFDMA cooperative system. Aiming at minimizing the total transmission power under target rate constraints for...
Abstract—In this paper we aim to solve the multiuser multiinput multi-output (MIMO) downlink beamforming problem. The transmitter is a multi-antenna base-station broadcasting to ...
Abstract— In this paper, a Dynamic Source Routing (DSR)based directional routing protocol is invoked for wireless ad hoc networks using directional antennas. This is designed to ...
— The bit error rate (BER) performance of single-carrier (SC) transmission in a frequency-selective fading channel can be significantly improved by using frequency-domain equaliz...
Virtual agents, to be expressive, not only need algorithms for displaying the subtleties of human behaviour, but also require environments and tools so that people can author them....
