摘要
由于第三代移动通信中承载业务种类的增加 ,对信道编码提出了更高的要求。Turbo码在Shannon极限附近有着优异的特性 ,是一种有效的通信信道编码方式 ,因此在宽带移动通信的IMT - 2 0 0 0体系中得到了广泛应用。简要叙述了Turbo码编译码的基本结构 ,重点介绍了在W -CDMA和CDMA 2 0 0 0中Turbo码的应用方案 ,以及Turbo码编码器单元。
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.
