【 摘 要 】

References(4)We propose a generalized frequency division multiple access (GFDMA) scheme which realizes a low PAPR characteristic compared with OFDMA, maintaining the sufficient capability of the frequency scheduling. GFDMA transmits the data with one or more frequency resources which can be divided into several pieces in the frequency domain. We can adaptively configure GFDMA between PAPR-oriented configuration like as SC-FDMA and throughput-oriented configuration like as OFDMA, depending on requirements. We focus on the investigation on the PAPR characteristic of GFDMA. Computer simulation confirms that GFDMA has a low PAPR property compared with OFDMA, still keeping sufficient frequency resource allocation capability.
