W.-Y. Shin, V. V. Mai, B. C. Jung, and H. J. Yang*, “Opportunistic network decoupling with virtual full-duplex operation in multi-source interfering relay networks,” accepted, Transactions on Mobile Computing. Abstract We introduce a new achievability scheme, termed opportunistic network decoupling (OND), operating in virtual full-duplex mode. In the scheme, a novel relay scheduling strategy is… Continue reading

[C09] H. J. Yang and J. Chun, “Zero-forcing-based two-phase relaying with multiple mobile stations,” in Proceedings on IEEE Asilomar Conference on Signals, Systems, and Computers, Pacific Groove, CA, Oct. 2008, pp. 351-355. Abstract It is well known that relay stations improve the link performance between the base and mobile stations and thereby improve the total system throughput. Nonetheless,… Continue reading
