Abstract :
A multi-carrier direct sequence code division multiple access (MC-DS-CDMA) system combined with frequency spread coding is proposed and investigated for the downlink. The proposed system exploits frequency diversity without additional redundancy by using frequency spread coding in a frequency-selective fading channel. Computer simulation results show its effectiveness in terms of average bit error rate and bandwidth efficiency. Furthermore, the proposed system is compared with a multi-carrier (MC)-CDMA system and a single-carrier (SC)-DS-CDMA system using a RAKE receiver
