| Abstract(in English) | Multi-Carrier Code-Division Multiple-Access(MC-CDMA) systems are considered to be potential for providing efficient multiple access for multimedia communications. It is necessary tosynchronize FFT timing, called symbol synchronizing, at the receive end in the MC-CDMA systems. Extremely low signal-to-noise ratio due to the multiple-access interference, however, do not allow us to employ a conventional symbol synchronizer used for ordinary OFDM systems. Moreover, we have to rely on the non-coherent detection before establishing the symbol synchronization because of difficulty in recovering the reference carrier. In this paper, therefore, we propose a symbol synchronizer based on envelope detection, in which the synchronization is established through correlation (despreading) and selection of the maximum correlated output. Basic characteristics of the proposed synchronizer are shown in the case of packet transmission. |
