Abstract

We have already proposed a hybrid single-carrier (SC) and multi-carrier (MC) system for next-generation mobile communication system. A SC signal has low peak-to-average power ratio (PAPR), which yields high power output for wide coverage. A MC signal is robust against frequency-selective fading and has high data rate with quadrature amplitude modulation (QAM). By appropriately selecting SC and MC signals, both high data rate and wide coverage system were attained in the proposed hybrid system. In this paper, uplink throughput of the proposed hybrid system was calculated using a computer simulation. Simulation results showed that the proposed system attained 20% higher throughput than conventional SC frequency division multiple access (FDMA) systems when the distance between the base station and a mobile station was 100 m. The proposed hybrid system also attained 52% wider coverage than conventional orthogonal frequency division multiple access (OFDMA) systems when throughput was 0.5 bit/s/Hz. single-carrier (SC), multi-carrier (MC), hybrid SC/MC system, peak-to-average power ratio (PAPR), system throughput
