Abstract

This paper discusses how the cognitive radio concept can be extended to allow the system not only to manage shared resources such as spectrum, but to use this knowledge to optimize the overall system power consumption. We introduce a case study of video over wireless via a 3G WCDMA modem connected to an H.264 decoder. We show that by utilizing knowledge about the communication channel, a savings of more than 20% of the overall system power is possible while maintaining a required quality of service. © 2007 IEEE.
