Abstract :
The multicarrier code division multiple access (MC-CDMA) technique is considered. Various spreading sequences have been taken into account, analyzed and compared with respect to their application in MC-CDMA systems. The analysis of the peak to average power ratio of the selected spreading codes is presented. The sensitivity of the MC-CDMA systems, using these codes, to the frequency offsets is analyzed. An interesting point of the analysis presented in the paper, is the computational complexity of MC-CDMA transmitter/receiver implementation
