Abstract

Abstract: A convolutional encoded orthogonal sequence multicode CDMA system is analyzed so as to transmit high rate data. For the high rate data of transimters' serial-to-parallel converted at first, and then the low rate data streams are convolutionally encoded and spreaded spectrum by a set of orthogonal sequence, all low branch data streams use a singal carrier. the performance of the system in AWGN channel is calculated, and numerical result is analyzed.

Key words: CDMA, convolutionally encoded, multicode M-ary/CDMA, AWGN channel
