| 摘 要： | 分析了现有的纠错信道编码技术,并对其进行了比较,说明了格状编码调制的纠错能力最强,但实现较困难;阐述了RS码和卷积码对突发错误有较强的纠错能力,交织码对连续冲激噪声也有很强的纠错能力,采用RS码结合交织、卷积码等纠正突发错误和随机错误的纠错方案是最佳方案;最后用一个数字电视中的纠错编码实例加以说明.

| Abstract: | The error- correcting ability of TCM is the best in the technology of error - correcting channel code , but it is relatively difficult to be realized. Read 2 Solomon and Convolution codes have very strong ability of suddenly Error - Correction, and Interlaced Code has very strong ability of continues Error - Correction. It is the best method to combine Read - Solomon Convolution codes and Interlaced Code in the system which needs continue suddenly error - correcting abihty in digital TV and communication , etc. The instance of error - correcting code in a digital TV is introduced lastly. |
