In this paper, Orthogonal Multicode OFDM-DS/CDMA system using Partial Bandwidth Transmission is proposed. By using the flexible carrier allocation of OFDM, Partial Bandwidth Transmission is considered for high quality communication. Furthermore, multicode packet data transmission is presented. Multicode packet data transmission is very effective to handle variable data. Since the proposed system can detect the header information without complex control, it is also suitable for packet data transmission. The computer simulation results show that the BER performance of the proposed system with the ideal channel estimation is improved compared with the case of the conventional Orthogonal Multicode DS/CDMA system with ideal RAKE receivers. Moreover the proposed system with the channel estimation by MLS algorithm also shows the good BER performance. In packet data transmission, the delay and throughput performances are also improved in the proposed system.
