The ability to provide accurate spectrum sensing and decision making under an uncertainty environment is proving useful for the military SATCOM to increases the spectrum utilization. Dynamic spectrum access(DSA) allows a secondary user to access the spectrum holes that are not occupied by the primary users. However, the spectrum sensing for DSA is normally performed in a complex SATCOM environment...
The allocation of bandwidth to unlicensed users, without significantly increasing the interference on the existing licensed users, is a challenge for Ultra Wideband (UWB) networks. Our research work presents a novel Rake Optimization and Power Aware Scheduling (ROPAS) architecture for UWB networks. Since UWB communication is rich in multipath effects, a Rake receiver is used for path diversity. Our...
The allocation of channel bandwidth without significantly increasing the interference among existing users is a challenge for the future UWB networks. Our research work presents a novel rake optimization and power aware scheduling (ROPAS) architecture for UWB networks. We propose to use cognitive radio (CR) for dynamic channel allocation among the requesting users while limiting the average power...
