Adaptive-TTCM-Aided Near-Instantaneously Adaptive Dynamic Network Coding for Cooperative Cognitive Radio Networks
— An Adaptive Dynamic Network Coding (ADNC) scheme conceived for Cooperative Cognitive Radio (CCR) is proposed for devising a novel ADNC-CCR system. The system is designed for supporting communications between multiple Primary Users (PUs) and a common Base Station (BS), where the independent source information is transmitted from the PUs to the BS with the aid of multiple Cognitive Users (CUs) acting as Relay Nodes (RNs). In order to facilitate the recovery of the source information at the BS, the CUs invoke the ADNC technique, which is assisted by our cooperative protocol operating by exchanging the CCR-based control information between near-instantaneously Adaptive Turbo Trellis Coded Modulation (ATTCM) and network coding codec as well as between the CUs and the BS. More particularly, nearinstantaneously ATTCM is employed for appropriately adjusting both the modulation mode as well as the code rate of the channel coding itself and of the network coding, according to the nearinstant...
