主要讲述了WIMAX和lte模式下前向纠错编码算法，重点讲述了TURBO算法的工作原理及优化-Focuses on the WiMAX and LTE mode, forward error correction coding algorithm, highlight the TURBO algorithm works and optimization

In the early nineties, turbo codes and its new iterative decoding technique were introduced, employing this new coding scheme and its decoding algorithm, it was possible to achieve performance within a few tenths of a dB the Shannon limit for a

princibe of turbo canal coding

Turbo codes were first proposed by Berrou (and others) in 1993. Since its introduction, turbo code has become the coding technique of choice in many communication and storage systems due to its near Shannon limit error correction capability. Thes
