Underlay cognitive Radio (CR) permits an unlicensed secondary users to transmit over the licensed spectrum unless the interference from the secondary users on the licensed, primary, receiver exceeds an acceptable level. This paper proposes an interference alignment-based distributed joint optimization design for multiple secondary transceivers in underlay CR case. The precoding and power allocation matrices are jointly optimized in the case of both perfect and imperfect channel knowledge to control the secondary interference on the licensed user and maximize the secondary rate. Numerical results prove that the proposed methods are able to support higher secondary rates and to protect the primary user from extra interference even in channel uncertainty case. |
