香农极限 meaning in English
shannonhartley theorem
Examples
- Construction of low - density parity - check code approaching the shannon limit
构造接近香农极限的低密度校验码 - Conventionally , dtv systems adopt coding schemes such as rs or convolutional codes , or concatenated codes , where the error correction performance is still quite far away from the shannon limit
通常的，数字电视系统采用的信道编码方案为rs码或卷积码，或二者的级联码，它的纠错性能与香农极限相比，仍有一定的距离。 - Turbo code was introduced by c . berrou in 1993 . turbo code can achieve the error correcting capacity close to the shannon - limit with reasonable decoding complexity , provided that the code words are long enough
1993年, c . berrou提出了一种新的信道编码方案? ? turbo码, turbo码能够在编码长度较长的情况下得到接近香农极限的纠错性能。 - Since their rediscovery , design , construction , decoding , analysis and applications of ldpc coded have become focal points of research . among them , the decoding algorithm and its implementation design are the focus of this thesis
Ldpc码是一种具有稀疏校验矩阵的线性分组码,研究结果表明,采用迭代的概率译码算法, ldpc码可以达到接近香农极限的性能。 - This class of codes decoded with soft - in soft - out ( siso ) iterative decoding performs amazingly well . since their rediscovery , design , construction , decoding , analysis and applications of ldpc coded have become focal points of research
