Stefan H. Müller–Weinfurtner Wireless Systems Research Dept., AT&T Labs – Research, 200 Laurel Avenue South, Middletown, NJ 07748, USA Abstract—The multiple antenna channel coding problem in Orthogonal Frequency–Division Multiplexing is reconsidered, because with frequency interleaving the effective channel characteristic across tones is rather fast fading and does not comply with the quasi–sta...

We present high resolution (R ∼ 44,000) UVES spectra of the eclipsing premain sequence star KH 15D covering the wavelength range 4780 to 6810 Å obtained at three phases: out of eclipse, near minimum light and during egress. The system evidently acts like a natural coronagraph, enhancing the contrast relative to the continuum of hydrogen and forbidden emission lines during eclipse. At maximum li...
