(A09) MOU Contract with G. Fettweis’ group (Vodafone Chair Mobile Communications Systems) @ TU Dresden as of Aug. 2016.
Abstract User association and resource allocation for downlink orthogonal frequency division multiplexing are jointly optimized in small cells networks with limited backhaul. In particular, per resource block resource allocation under the backhaul constraint is formulated in pursuit of maximizing proportional fairness, which leads to an integer problem requiring prohibitive computational complexity to solve. We… Continue reading
[C23] W. Park and H. J. Yang*, “On spectral efficiency of asynchronous GFDMA and SC-FDMA in frequency selective channels,” in Proc. IEEE Vehicular Technology Conference (VTC), May 2016. Abstract In the fifth generation mobile communication, futuristic wireless services such as remote surgery, steaming gaming, tactile internet, and augmented reality are envisioned, which require real-time end-to-end… Continue reading
W. Park, H. J. Yang*, and H. M. Oh, “Sum-rates of asynchronous GFDMA and SC-FDMA for 5G uplink,” ICT Express, vol. 1, no. 3, pp.127-131, Dec. 2015 Abstract The fifth generation (5G) mobile envisions ultra-low latency less than 1ms for end-to-end communications. To this end, frameless asynchronous multiple-access may be needed to allow users to… Continue reading
[C19] W. J. Park and H. J. Yang, “System-level performance evaluation of multi cell two-way relay networks with fractional frequency reuse,” in Proc. International Conference on ICT Convergence (ICTC), Busan, Korea, Oct. 2014, pp. 936-940. Abstract Two-way relaying has been known to double the spectral efficiency of the one-way relaying scheme in a single cell system. In this paper, we observe… Continue reading
