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… CONTINUE READING
