摘要
作为3G标准之一的TD-SCDMA系统,它的物理层协议对传输格式组合指示TFCI采用了双正交编码方法,但是标准中没有规定具体的译码算法。文中提出了一种在其编码方法的基础上简单高效的译码算法——基于最大TFCS的TFCI译码算法。其效率高,误码率低,性能较一阶Reed_Muller译码和快速哈达码变换译码有很大提升。
As one of the 3G standards, Physical layer protocol of TD-SCDMA uses double orthogonal encode for transport format combination indicator（TFCI）. The specific decoding algorithm hasn＇t appeared in standards. A simple and efficient decoding algorithm is proposed in this paper, that is, the TFCI decodingalgorithm based on maximum TFCS. The algorithm has high efficiency and lower error rate, and better performance as compared with the first-order Reed_muller decoding and fast hadamard transformation.
