A CPS is defined as integration of computation and physical processes. In cps, downsized and embedded devices execute physical processes by monitoring and controlling entities in the physical world. Service-oriented architecture (SOA) provides the concept of packaging available functionalities as interoperable services. Services can be used to construct applications. But, in the context of cyber-physical...
In cooperative spectrum sensing, the detection performance is affected seriously by the error of channel estimation. Hence, the accurate channel estimation is very necessary. In this paper, the performance of cooperative spectrum sensing under the LMMSE channel estimation method with time-domain windowing technique is analyzed. Simulation results show that the probability of detection can reach high...
The combination of ultra-wideband technique and cooperative technique can improve the performance of ultra-wideband communications effectively and reduce the power consumption. In order to improve the system performance as well as reduce the hardware cost, a cooperative ultra-wideband system model using transmitted reference receiver and decode-and-forward (DF) relay protocol is proposed, and normalized...
