Relay-Assisted Primary and Secondary Transmissions
In this paper, we investigate the use of N cognitive relays to assist primary and secondary transmissions in a timeslotted cognitive setting with one primary user (PU) and one secondary user (SU). We propose an overlapped spectrum sensing strategy for channel sensing, where the SU senses the channel for τ seconds from the beginning of the time slot and the cognitive relays sense the channel for...
متن کاملCooperative overlay secondary transmissions exploiting primary retransmissions
We introduce an overlay cooperative cognitive radio scheme, in which the secondary network transmits only during the retransmissions of the primary network. The secondary network makes use of multiple relays in order to increase its performance compared to a non-cooperative scenario. Moreover, the secondary operates without harming the performance of the primary network. Different cooperative p...
متن کاملPrimary and Secondary Tumors of the Sternum
Sternal tumors are very rare and challenging. Secondary sternal tumors are more common than primary tumors. These tumors are usually refractory to chemotherapy and radiotherapy, and surgery is the best choice for their treatment. In this study, we reported the collected data of 15 patients with primary and secondary tumors of the sternum, histological type, as well as kind of resection and reco...
متن کاملReal-Time Traffic Transmissions Over the Internet
Multimedia applications require the transmission of real-time streams over a network. These streams often exhibit variable bandwidth requirements, and require high bandwidths and guarantees from the network. This creates problems when such streams are delivered over the Internet. To solve these problems, recently, a small set of differentiated services has been introduced. Among these, Premium ...
متن کاملOutage performance of relay-assisted primary and secondary transmissions in cognitive relay networks
In this paper, a two-phase protocol for relay-assisted spectrum sharing in cognitive relay network is proposed. The primary system comprises a transmitter-receiver pair (PT-PR) and a decode-and-forward relay (Relay), while the secondary system comprises a transmitter-receiver pair (ST-SR). In the proposed protocol, the Relay assists the transmissions of the primary users as well as the secondar...
