摘要： A turbo encoded H-ARQ system and an error detection method are disclosed, and more particularly, a turbo encoded H-ARQ system and an error detection method that lower an undetected error probability and frame error rates by increasing the degree of an equivalent CRC generator polynomial by using a modified trellis termination. It has been made possible to obtain an equivalent CRC generator polynomial having higher degree than the related art CRC generator polynomial by employing a modified trellis termination. This achieved a lower undetected error probability than the related art undetected error probability by using an equivalent CRC generator polynomial having higher degree. This also achieved lower frame error rates, when the same number of overhead bits are used, due to the lower undetected error probability.

摘要翻译： 公开了turbo编码的H-ARQ系统和错误检测方法，更具体地，公开了一种涡轮编码H-ARQ系统和错误检测方法，其通过增加等效CRC产生器的程度来降低未检测到的错误概率和帧错误率 通过使用修改的网格终止多项式。 通过采用改进的网格终止，已经可以获得具有比现有技术CRC生成多项式更高程度的等效CRC生成多项式。 通过使用具有较高程度的等效CRC生成多项式，这实现了比相关技术未检测到的错误概率更低的未检测到的误差概率。 当使用相同数量的开销比特时，由于较低的未检测到的错误概率，这也实现了较低的帧错误率。
