摘要
Turbo码采用了随机交织器、打孔删除、栅格终止、软输入软输出迭带译码等新技术 ,可以有效改善数字信号在传输技术过程中由于各种噪声和干扰造成的误差 ,提高系统的可靠性 ,是第三代移动通信系统数字基带传输技术的重要组成部分。在介绍 Turbo码的基本原理及其优良性能的基础上 。
Having adopted some new technologies such as interleaver, puncturing,trellis termination,softin/soft out iterative decoder and so on,Turbo code can efficiently get over the errors which are caused by different kinds of noise when the digital signals is transmitted,and the reliability of system can be improved accordingly.In 3G mobile communition system,Turbo code has been an important part of the transmit technology of digital baseband. This paper introduces the theory and the advanced character of Turbo code,and puts emphasis on its application in the third generation mobile communication system.
