From the sequence correlation requiring of Turbo codes coding and decoding, correlation of sequence is proposed as a criterion to design interleaver, a good interleave scheme called clinodiagonal interleaver is obtained.

從Turbo碼距離特性解釋了Turbo碼的性能精品免费观看69影院，由于分量碼采用遞歸系統(tǒng)卷積碼，具有碼距拖尾性免费播看30分钟大片，使得交織器長度為N的Turbo碼能使誤碼率降低到卷積碼的1/N国产视频色色色。

Based on optimizing the interleave algorithm of 3GPP, a turbo encoder is implemented using FPGA technique.

在對3GPP的交織算法進行優(yōu)化的基礎上，基于FPGA技術實現了Turbo碼編碼器男女黄色网站视频；在對用Max-Log-MAP算法進行優(yōu)化的基礎上色色色综合五月天，基于DSP技術實現了Turbo碼的譯碼器；最后通過接口實現了一個完整的Turbo碼編99尤物无码国产福利在线观看、譯碼系統(tǒng)干逼视频。

The general decoding method for Turbo codes provided by the invention adopts enhanced Max-Log-MAP algorithm, makes use of Max-Sum semiring property in the generalized distribution law and combines and simplifies measure and calculation of forward and backward status of traditional binary Turbo codes, which means combining grid graph of traditional binary Turbo codes in nature to ensure that the status measure and calculation of the traditional binary Turbo codes have the same calculation expression way with that of the duobinary Turbo codes so that a general decoding device can both decode the traditional binary Turbo codes and duobinary Turbo codes.

本發(fā)明提出的Turbo碼通用譯碼方法采用增強型Max-Log-MAP算法，利用廣義分配率中的Max-Sum半環(huán)性質殴美aaaav，對傳統(tǒng)二進制Turbo碼的前向和后向狀態(tài)度量計算進行合并簡化99久久国产亚洲精品观看，從本質上也就是對傳統(tǒng)二進制Turbo碼的網格圖進行合并，使得傳統(tǒng)二進制Turbo碼的狀態(tài)度量具有和雙二進制Turbo碼一樣的計算表達方式114毛片，從而使得通用譯碼裝置對于傳統(tǒng)二進制Turbo碼和雙二進制Turbo碼都可實現91三级片在线。
