Abstract

The throughput of multicast networks depends not only on the transmission rate, but also on the number of receivers simultaneously served by the transmit signal. In this letter, we develop a cross-layer approach based on joint multicast beamforming and rate aware instantly decodable network coding (J-MB-RA-IDNC), where instantly decodable network coding (IDNC) is employed at the network layer to increase the number of receivers to be served simultaneously, multicast beamforming is used at the physical layer to direct the beam toward the targeted receivers of the selected rate aware IDNC (RA-IDNC) schedule to improve the transmission rate. Simulation results demonstrate the effectiveness of our proposed scheme.

通过联合组播波束形成和速率感知即时可解码网络编码提高组播网络吞吐量

组播网络的吞吐量不仅取决于传输速率，还取决于发送信号同时服务的接收端数量。在这篇文章中，我们开发了一种基于联合组播波束形成和速率感知即时可解码网络编码（J-MB-RA-IDNC）的跨层方法，其中在网络层使用即时可解码网络编码（IDNC）来增加同时服务的接收器数量，在物理层使用组播波束形成来将波束引导到所选速率感知IDNC （RA-IDNC）计划的目标接收器以提高传输速率。仿真结果验证了该方案的有效性。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
