Nonregenerative MIMO relaying with optimal transmit antenna selection
FREE-DOWNLOAD S Peters… – Signal Processing Letters, research, We derive optimal SNR-based transmit antenna selec- tion rules at the source and relay for the nonregenerative half-du- plex MIMO relay channel. While antenna selection is a suboptimal form of beamforming, it has the advantage that the optimization is tractable
Enhanced directional excitation and emission of single emitters by a nano-optical Yagi-Udaantenna
FREE-DOWNLOAD TH Taminiau, FD Stefani… – Opt. Express, 2008 We demonstrate by 3D numerical calculations that the interaction of a single quantum emitter with the electromagnetic field is both enhanced and directed by a nano-optical Yagi-Uda antenna. The single emitter is coupled in the near field to the resonant plasmon mode of
A novel compact ultra-wideband (UWB) wide slot antenna with via holes
FREE-DOWNLOADD Chen… – Progress In Electromagnetics Research, Ultra-wideband (UWB) wireless communication technology has been receiving wide attention from both academy and industry since the Federal Communication Commission (FCC) released of the frequency band from 3.1 to 10.6 GHz for commercial communication applications in
