Superposition data transmission for cognitive radios: Performance and algorithms

Abstract

For improvement of achievable rate region in cognitive radio channels, a transmission method for secondary users is proposed. At first, the rate region of the sensing based cognitive radio scheme in which secondary users access the channel based on their channel sensing results with sensing error is analyzed. In the multiuser information theory, it is well… (More)
