| Abstract: | In this paper, a convolutional enceded orthogonal sequence multicode CDMA system is proposed so as to transmit user's high rate data to fit the requirement of the services of the future mobile communication. Similar to multicarrier modulation, the higher rate date transmitted by serial-to-parallel is converted at first, and then the lower rate data streams are convolutionally encoded and spreaded spectrum modulated by a set of orthogonal sequence Being different from multicarrier modulationg, all lower branch data streams use single carrier. The performance of the system over Nakagami fading channel is calculated, and numerical result is analyzed. |
