“Layered Relaying for Wireless Multicast: System Design and Experimental Evaluation using SDRs
Relaying in wireless networks can lead to better coverage, higher throughput, and improved quality of service. The most popular of relaying strategies, as employed in LTE-Advanced and IEEE 802.16m, is the so-called two-hop decode-forward approach. In this talk, we will give an overview of a novel relaying scheme that provides considerable performance gains over two-hop decode-forward without incurring the practical issues typically associated with more advanced relaying strategies prevalent in the research literature.
In addition to presenting an overview of the proposed scheme, its system design and experimental evaluation, the speaker will highlight the importance of translating communications research into experimental prototypes using software-defined radios, and share his group’s learning experience in this domain.
