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

Yang, “A Study on the PAPR Reduction Using Selective Mapping in GFDM,” in Proc.  Conference on KICS, Seoul, Korea, Nov. 2015.   Abstract 기존 직교 주파수 분할 다중방식 (orthogonal frequency division multiplexing; OFDM)에서는 Peak to Power Ratio (PAPR)을 줄이기 위해 다양한 방법들을 써왔다. 그 중에서 선택사상기법 (selective mapping; SLM) 을 이용한 PAPR 감소… Continue reading

NI Hands-on seminar and practice for 5G network research

At June. 30, the NI technical seminar & practice were held in UNIST.  The Software Defined Radios (SDN) is have emerged as a viable prototyping option for next generation wireless research. After introducing about NI SDN, the practice was proceeded using LabVIEW comms/ Universal Software Radio Peripheral (USRP) reconfigurable I/O(RIO) system. The main activities were focused on understanding algorithm for Field-programmable gate array… Continue reading
