RESUMO

In this dissertation, a study of an orthogonal multicarrier DS-CDMA multiple access system is presented lhe performance of the system in a multipath Rayleigh fading channel was analyzed through computer simulation. The performance gains through the use of channel state information in the system were obtained Two channel coding schemes for the studied system were suggested. The schemes provide considerable gain of performance, without reducing the transmission rate of information or increasing the transmitted signal bandwidth
