OFCDM - A promising wireless multiple access technique for 4G mobile communications

Future mobile communication systems aim to provide extremely high speed data transmission, especially in downlink. The broadband orthogonal frequency and code division multiplexing (OFCDM) system with two-dimensional spreading (time and frequency domain spreading) is becoming a very promising technique for high speed wireless communications due to its advantages over OFDM. This talk presents the features, basic structure and main functions of the OFCDM system. It will be shown that the OFCDM is superior to OFDM.
