, one radio can transmit or receive only at one channel at a specific time. The new relay-…

… However, the relay nodes in our cooperative relay in cognitive radio networks play a different
role … Instead of maximizing transmission rate in multi-hop ad hoc networks, we focus on the …

… a cooperative relaying framework in which the primary users select the secondary users that
may have better channel conditions as cooperative relays to … a simple cooperative relaying …

… relay-based heterogeneous network (HCRHeNet) to support both unicast and multicast
services, where hierarchical cooperative relay … of heterogeneous radio networks. The underlined …

… In [4], we study the use of cooperative relays for secondary transmissions and illustrate that,
… cognitive radio system with high data rates is achievable by using cooperative relays for both …

… for cooperative relay in a three-node cognitive radio network. Different from conventional
cooperative relay channels, cognitive radio relay … , dual-hop, and relay channels, which provide …

… , and delay of wireless cooperative communication. In our view, these benefits make
cooperative wireless networks capable of combating radio unreliability and meeting future …

… Hence cooperative relay can enhance the performance of the CR system. OFDM-based
CR networks with cooperative relays attract much attention in both academia and industry …

… self-sustainable wireless networks. We then introduce a hybrid radio design that integrates
… specific hybrid radio network in which hybrid radios act as passive relays to backscatter the …

… In order to make efficient use of such diversity in both spectrum and space, we propose a
novel cooperative relay scheme (CRS). We introduce a cooperative node to relay the data from …
