仿真分析了迭代次数对Turbo编码性能的影响,包括对误比特率(BER)和误帧率(FER)的影响。并通过对附加信息的距离变化进行度量,提出了一种新的迭代停止判断准则,这种准则能动态地选择迭代次数。
By programming emulator,transmission of Turbo codes is simulated with different iterative decoding times parameter, which has very important influence in its performances such as BER and FER. This paper also proposes a simple iteration-stop- ping criterion that can choose iteration stopping criteria dynamically.
