Study on multi-Carrier CDMA systems based on poly-phase Orthogonal sequences

MC-CDMA (Multi-Carrier CDMA) is an integrated technology of OFDM (Orthogonal frequency-division multiple access) and CDMA (Code-division multiple access). This technology is considered as the core technology of the future communications, because it keeps the advantages of OFDM and CDMA. The fundamental principles of transmitter and receiver of MC-CDMA are analyzed in the paper firstly. Then MC-CDMA system models are simulated with MALAB. Using poly-phase orthogonal sequence wave as the spread spectrum sequences in MC-CDMA system, original data can be recovered, through the AWGN Channel.
