dc.description.abstract | Orthogonal frequency division multiplexing (OFDM)
is considered as one of the most promising techniques for next generation mobile systems. When the OFDM is applied to cellular environments, it may suffer from so-called other-cell interference (OCI). In this paper, we propose a novel resource allocation scheme in OFDM-based asynchronous cellular systems. It can reduce the OCI by exploiting the repetitive property of a cyclic prefix (CP) of OFDM symbols. The proposed scheme can be applied to OFDM-frequency division multiple access (FDMA) and OFDM-code division multiple access (CDMA) systems. Computer simulation results show that the proposed scheme can reduce the OCI by nearly up to 1dB in a typical cellular OFDM environment, compared to the conventional scheme. | en |
