In this paper, we discuss a potential multiple access and modulation scheme based on polarized states (PS) of electromagnetic (EM) waves for line-of-sight (LOS) communications.
The article "Polarization Division Multiple Access With Polarization Modulation for LOS Wireless Communications" by Bin Cao, Qin-Yu Zhang, and Lin Jin discusses a potential multiple access and modulation scheme based on polarized states of electromagnetic (EM) waves for Line-of-Sight (LOS) communications.
He had an unrelenting fondness in Iowa for saying that the "amber waves of grain" line in "America the Beautiful" could refer to corn.
Barclays said: BT investors have ridden a wave of buoyant fixed line market and cost cutting which has provided three years of material earnings growth and share price outperformance.
The programs will be backed by a first-ever television advertising campaign -- a $6 million effort that begins Sept. 1 -- along with a wave of promotions, a line of 16 new toys (like "Move 'N Groove Dance Mat Barney") from Fisher-Price and a 70-city nationwide stage tour starting in January.
announced Monday that he now backs gay marriage, becoming the latest in a wave of Senate Democrats lining up to express their support.
They discovered that, by shifting the "phase" of light so that the peaks of one wave line up with the valleys of an adjacent wave, the two waves cancel each other out, creating "shadows" between waves that are smaller than the waves themselves(see chart).
The solid line indicates the magnitude of the P wave, broken line is that of S wave, and dotted line shows the period during which the magnitude is kept unchanged around the S wave arrival.
They discovered that by shifting the "phase" of light so that the peaks of one wave line up with the valleys of an adjacent one, the two cancel each other, creating "shadows" between waves that are smaller than the waves themselves(see diagram, p. 141).
