Optimizing Coexistence System with Interference Temperature for Multi-user Environments
Joo-Pyoung Choi, Won-cheol Lee · ITC-CSCC :International Technical Conference on Circuits Systems, Computers and Communications · 2008
We explore the coexistence potential of cognitive system based on interference temperature. The characteristic feature of this interference temperature metric would be their ability to adapt the transmit power and bandwidth of their communication scheme to maximize the QoS for the secondary users while minimizing the interference to the primary users. Considering generalized interference temperature model as a baseline [2], we investigate the throughput variation of the secondary user in the heterogeneous communication environment. Also we propose a certain coexistence scheme that allocates bandwidth and transmit power of secondary user without harming the primary user using the concept of interference temperature.
