[d04] Hyunmyung Oh and Hyun Jong Yang. “PAPR Reduction Scheme Using Selective Mapping in GFDM” The Journal of The Korean Institute of Communication Sciences, 41.6 (2016.6): 698-706. Abstract 기존 직교 주파수 분할 다중 방식 (orthogonal frequency division multiplexing; OFDM)에서는 최대전력 대 평균전력 비 (peak to average power ratio; PAPR)가 높아 회로 설계에 대한 어려움과, 신회 왜곡… Continue reading

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
