Abstract :
A multi-carrier (MC) modulation technique has been incorporated into CDMA systems for reason of high data rate transmission, bandwidth efficiency, frequency diversity, interference reduction and so on. We propose a new signal combining scheme for soft handoff in mobile MC-CDMA systems considering the characteristics of MC-signal in a frequency selective fading channel
