High-speed communication over short distances using sub-nanosecond pulses, rather than conventional sinusoidal waves, has paved the way for cheap wireless transceivers, capturing the imagination of both academics and engineers in industry alike. Ultra Wideband Signals and Systems in Communication Engineering focuses on the basic signal processing that underlies current and future ultra wideband systems ensuring this text will be essential reading even as UWB applications mature and change or regulatio 606 $aUltra-wideband devices 606 $aSignal processing 606 $aBroadband communication systems 606 $aAntenna arrays 615 0$aUltra-wideband devices. 615 0$aSignal processing. 615 0$aBroadband communication systems. 615 0$aAntenna arrays. 676 $a621.382 700 $aGhavami$b M$0892233 701 $aMichael$b L.
