In this paper, we focus on the designing of automatic repeat-request (ARQ) protocols for the two-way wireless relay systems. According to different feedback schedules, we propose three basic ARQ protocols to improve the throughput of two-way relay systems, namely, relay-only ARQ (Ro-ARQ), terminal only ARQ (To-ARQ) and relay-terminal ARQ (RT-ARQ). Through analyzing the outage throughput of these three ARQ protocols, it is verified that all three protocols can improve the system performance. In addition, simulation results reveal that the RT-ARQ protocol has the closest performance to the theoretical throughput upperbound among all given methods without severe deterioration on system complexity. <\/jats:p>","DOI":"10.1155\/2012\/980241","type":"journal-article","created":{"date-parts":[[2012,6,22]],"date-time":"2012-06-22T14:27:58Z","timestamp":1340375278000},"page":"980241","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["ARQ Protocols for Two-Way Wireless Relay Systems: Design and Performance Analysis"],"prefix":"10.1177","volume":"8","author":[{"given":"Zhenyuan","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering and Information Science, University of Science and Technology of China, Hefei 230027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiushi","family":"Gong","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering and Information Science, University of Science and Technology of China, Hefei 230027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Xi'an Jiaotong University, Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guo","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering and Information Science, University of Science and Technology of China, Hefei 230027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,6,21]]},"reference":[{"key":"B1-2012-980241","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2010.5675781"},{"key":"B2-2012-980241","doi-asserted-by":"publisher","DOI":"10.1155\/2009\/618787"},{"key":"B3-2012-980241","doi-asserted-by":"publisher","DOI":"10.1145\/1282380.1282425"},{"first-page":"358","volume-title":"Proceedings of the 12th Annual International Conference on Mobile Computing and Networking (MOBICOM \u203206)","author":"Zhang S.","key":"B4-2012-980241"},{"key":"B5-2012-980241","doi-asserted-by":"publisher","DOI":"10.1109\/IZS.2006.1649085"},{"key":"B6-2012-980241","doi-asserted-by":"publisher","DOI":"10.1109\/ICC.2008.204"},{"key":"B7-2012-980241","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2008.929913"},{"key":"B8-2012-980241","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2010.2081985"},{"key":"B9-2012-980241","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2011.2146710"},{"key":"B10-2012-980241","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2010.090210.091464"},{"key":"B11-2012-980241","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2008.12.038"},{"first-page":"180","volume-title":"Proceedings of the 18th International Conference on Software, Telecommunications and Computer Networks (SoftCOM \u203210)","author":"Vien Q.
