Pulse Shaping for Impulse Radio UWB
There are many ways how to increase quality of service (QOS) or the number of wireless users in the shared spectrum of modern wireless communication. It is possible to use better modulation schemes or multiplexes, but all of these techniques do not constitute a dynamic solution. A more intelligent solution of the spectrum access gives us the potential to solve these spectrum problems. Cognitive...
متن کاملInterference Mitigation Technique for Coexistence of Pulse-Based UWB and OFDM
Ultra-wideband (UWB) is a useful radio technique for sharing frequency bands between radio systems. It uses very short pulses to spread spectrum. However, there is a potential for interference between systems using the same frequency bands at close range. In some regulatory systems, interference detection and avoidance (DAA) techniques are required to prevent interference with existing radio sy...
متن کاملPulse Shaping Filter Design and Interference Analysis in UWB Communication Systems
Ultra wideband (UWB) is a promising technology for short range and high-speed wireless communications such as home entertainment, wireless video downloading, wireless LAN, wireless USB and so on. This dissertation studied several important issues in the application of UWB technology and its contributions are summarized as follows. First, a 2-stage optimal UWB pulse shaping filter design procedu...
متن کاملUWB Impulse Radio Waveform Shaping Techniques for Narrow-Band Interference Rejection
-In ultra-wideband (UWB) impulse radio (IR) technology, it is important that the pulse shape be adjusted such that the power spectral characteristics not only satisfy the standard limits, but also be characterized by deep nulls at the locations of existing narrowband primary users. Cognitive Radio Technology (CR) is presented as a viable solution for UWB systems for narrowband interference supp...
متن کاملImpulse radio pulse shaping for ultra-wide bandwidth (UWB) systems
In this paper, we investigate the design of pulse shaping FIR filters for impulse radio ultrawideband (UWB) communications systems. The goal of the shaping is to meet an arbitrary spectrum mask, e.g., the mask mandated by the FCC for UWB emissions. Compared with classical FIR filter designs, the current problem introduces three new challenges: (1) it is minimax with quadratic constraints, (2) a...
