Abstract

High transmission bandwidth efficiency in mobile communication can be produced by schemes such as direct sequence code division multiple access (DS/CDMA) and orthogonal frequency division multiplexing (OFDM). The combination of OFDM signaling and CDMA scheme has one major advantage that it can lower the symbol rate in each subcarrier so that longer symbol duration makes it easier to quasi-synchronize the transmission.
