Joint Sensing-Channel Selection and Power Control for Cognitive Radios

  title={Joint Sensing-Channel Selection and Power Control for Cognitive Radios},
  author={Xin Wang},
  journal={IEEE Transactions on Wireless Communications},
We consider joint optimization for sensing-channel selection and ensuing power control problem with cognitive radios over time-varying fading channels. It is shown that this joint design can be judiciously formulated as a convex optimization problem. Optimal joint sensing-channel selection and power control scheme is then derived in closed-form under the constraints of average power budget and maximum allowable probability of collisions with the primary communications. In addition, we develop a… CONTINUE READING
