Photospheric structure in solar-type stars,in providing a complex environment awareness, avoiding the enemy jamming and deception and improving the anti-interference ability of the system as a whole. Based on the analysis of the existing problems on the basis of spatial information system construction, this paper integrates cognitive technol

Solar and stellar chromospheres,sts of a primary transmission (PT) node, a primary receive (PR) node, a multi-antenna secondary transmission (ST) node and a secondary receive (SR) node. Two-phase transmission protocol with variable time is used in our proposed scheme. The first phase is used for PT to transmit its signals to ST an

Besides, primary system obtains a better performance.

Cooperative Spectrum Sharing for Multi-antenna Cognitive Networks with Joint Time and Power Allocati and study the joint optimal time and power allocation to maximize the secondary transmission rate under the condition that primary system can achieve the target rate. The simulation results show the scheme is feasible and has a better performance compared with a fixed time allocation.
