Abstract
Future mobile communication systemsaim 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 paper presents the basic structure and main functions of the OFCDM system. A novel detection method for the OFCDM, called hybrid multicode interference (MCI) cancellation and minimum mean square error (MMSE) detection, is described. It has been shown in this paper that OFCDM is superior to OFDM.
