研究目的
To propose a flexible orthogonal frequency division multiplex (OFDM)-based modulation scheme named Flexible Configured OFDM (FC-OFDM) for future 5G networks, enabling flexible subband configuration and targeting a multi-service scenario.
研究成果
The FC-OFDM scheme is proposed as a flexible solution for 5G multi-service environment, compromising the advantages and drawbacks of the CP-OFDM and FBMC schemes. It enables flexible configuration of different subbands characters, suitable for diverse requirements in future 5G networks.
研究不足
The scope of the paper is limited to the downlink transmission only. The complexity increase at the base-station side is mainly due to the doubled FFT rate, and the spectral efficiency is affected by the redundant samples in the time domain for the CP and RI.
