In this paper, a new multiple access scheme called Frequency Interleaved Code Division Multiple Access (FICDMA) is proposed. The major novelty of this scheme is that it is able to benefit from the advantages of the well known Multi-Carrier Code Division Multiple Access (MC-CDMA) and to solve one of the major drawback encountered by OFDM-based techniques, the fluctuations of the transmitted signal, represented by the Peak-to-Average Power Ratio (PAPR). Now-a-days, some of the most promising technologies for the air interface of the Fourth Generation (4G) terrestrial systems, concerned by flexibility and very high spectrum efficiency, are Multi-Carrier Spread-Spectrum techniques (MC-SS).
