摘要：
Orthogonal frequency division multiple access (OFDMA) is a promising access technology based on multiple carrier transmission. In this paper, we develop a power and bits allocation scheme for multiuser OFDMA to minimize the system margin according to channel state information (CSI). Compared with other OFDM methods, our scheme has higher system capacity and better BER performance.
