| Abstract: | As more hosting services have been introduced in the third generation mobile communication, the technique of channel coding is required to possess a better performance. Turbo code shows an excellent performance close to Shannon's performance limit. With its effective channel coding, it has been widely used in the IMT-2000 system of broadband mobile communications. This paper briefly describes the structure of the Turbo code, with the emphasis on the application scheme of Turbo code in W-CDMA and CDMA 2000, and the configuration of Turbo coding unit and interlacing unit. |
