Comparison of Different Subchannelization Modes for OFDMA
2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007In this paper, the problem of subchannel composition and allocation for the downlink of an OFDMA system is investigated. The subchannelization mode FUSC adopted in 802.16 is described and compared with dynamic subcarrier allocation algorithms. Performances are evaluated regarding spectral efficiency and complexity.

Equalization for OFDMA Systems Exploiting Unused Subchannels
2005 IEEE 16th International Symposium on Personal, Indoor and Mobile Radio Communications, 2005In orthogonal frequency division multiple access (OFDMA) systems, the cyclic prefix (CP) length needs to be no less than the longest channel delay spread of many users, reducing bandwidth efficiency more significantly than in single user OFDM systems.
