In most communication system, multiple users need to be supported. In OFDM systems, multiple access is achieved through combining TDMA and FDMA. OFDM supports multiusers with popular multiple access schemes, these schemes are MC - CDMA and OFDMA. In this paper we propose a precoding based approach to multiple access in OFDM systems using singular value decomposition (SVD). The scheme is like a CDMA scheme, in that the entire bandwidth can be used at all times, except that it does not entail expanding the bandwidth. This scheme combats the Multiuser Interference (MUI) caused by other users. ©2007 IEEE.
