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 regulatioUltra-wideband devicesSignal processingBroadband communication systemsAntenna arraysUltra-wideband devices.Signal processing.Broadband communication systems.Antenna arrays.621.382Ghavami M892233Michael L.
