Robust Power Control Under Location and Channel Uncertainty in Cognitive Radio Networks

In this letter, we consider the power control problem in cognitive radio (CR) networks when both primary user (PU) location and wireless channel are unknown. Prior work in power control assumes perfect knowledge of PU and CR locations, which is not practical due to localization errors and node mobil...
