  1. Hard decision decoding

    硬判決譯碼
  2. Since soft - decision decoding needs much more computation, it is so complex as to be infeasible in many applications

    但是軟判決譯碼比硬判決譯碼要進行更多的譯碼計算，復雜度較高，從而限制了它的應用范圍。
  3. Chapter five discusses de - mapping and soft information extraction in dvb - t receiver and gives the performance comparison of soft decision decoding and hard decision decoding

    第五章首先介紹軟判決的基本原理，然後分析軟信息提取及解映射的過程，最後給出了軟判決譯碼和硬判決譯碼的性能模擬結果。
  4. The viterbi decoder with hard decision designed by the paper, is aimed at ( 3, 1, 9 ) convolutional coding. the data rate is 9. 6kbps. the data rate received by the rake receiver is spreaded by 127 - bit spread sequences, added pilot signals and modulated by qpsk

    該課題所設計viterbi譯碼是針對（ 3 ， 1 ， 9 ）卷積碼的硬判決譯碼，數據速率為9 . 6kbps ; rake接收機所接收的數據是擴頻因子為127 、加入導頻且經qpsk調制的擴頻信號，使用verilg硬體描述語言在xilinx公司的ise環境下在用現場可編程門陣列（ fpga ）來實現viterbi譯碼器和rake接=收機的功能。
  5. Based on tanner graph, the representation and construction of ldpc codes are addressed, and the two decoding algorithm for ldpc codes, i. e, bit - flipping algorithm and sum - product algorithm, are discussed. from two aspects - minimum distance and the failure of independence assumption, the impacts of cycles to the performance of ldpc codes are analyzed. 2

    基於tanner圖模型，詳細介紹了ldpc碼的表示和構造；介紹了ldpc碼的硬判決譯碼（比特翻轉演算法）和軟判決迭代譯碼（和積演算法） ；從最小距離和獨立性假設失效兩個方面分析了環的存在對ldpc碼譯碼性能的影響； 2
  6. For practical implementations, simpler decoding algorithms have been suggested. this decoder implements iterative decoding of tpcs using a soft - input hard - output decoder, followed by reliability calculations to obtain oft - decisions from the hard - output of the decoder. the performance of this decoder is nearly optimal and thus the decoding strategy presents a good compromise

    針對實際應用中存在的計算復雜問題，在重復譯碼實現中採用軟進/硬出的簡化演算法，用可靠度估計從硬判決輸出中獲得軟信息，從而使譯碼器在性能優越和計算簡便之間獲得了一個很好的折中，並通過硬體實現了tpc的實時解碼，在低信噪比（ eb / n0 ）的條件下取得了非常低的誤碼率。
