Last year, the group demonstrated that the speed of a wireless link in the 300 - GHz band could be greatly enhanced by using quadrature amplitude modulation (QAM). (sciencedaily.com)
«Our primary interest is in extending the approach to work with more complex signals such as quadrature PSK», which can encode more data in the phase, says Richardson. (newscientist.com)
The point is we are probably now 2 generations into rules based advice and quadrature optimization and it already overtaking this PC product so choosing a guesstimated simple portfolio when you can have an optimized slightly more complex kind of misses the power we now have. (actuaryonfire.com)
