Abstract

A novel convolutional code spread scheme for multi- carrier system with high diversity gain is proposed in this paper. This scheme, named by convolutional code spread multicarrier (CCSM), convolutionally spreads the data symbols onto several consecutive subcarriers with complementary sequences. Compared with the traditional OFDM and OFDM-CDM systems, CCSM enjoys high BER performance with equivalent spectrum efficiency in multipath Rayleigh fading channels. Moreover, the special structure of convolutional spreader in CCSM makes the system suitable for high order modulation, which undoubtedly endows the CCSM with the attractable capability of high transmission capacity.
