Abstract

The principle of CDMA mode in TD-SCDMA(TD), which means how spectrum spreading and scrambling code being used in TD is a basic problem. Comparing with the other two 3G standards, the principle and realization of the CDMA mode used in TD standard has much difference. Both cdma2000 and FDD WCDMA use the CDMA mode of real spectrum spreading and complex scrambling code, which is the traditional concept of spectrum spreading and scrambling code. While there are the principle and realization of complex spectrum spreading, weighted coefficient and dedicated complex scrambling code in TD, which would be explained in this paper. Also the implementation circuit and performance analysis of the CDMA mode used in TD would be presented in this paper.
