| 摘 要： | 3GPP的物理层协议中对传输格式组合指示TFCI采用了类Reed-Muller编码,但没有具体解释其编码方法和译码算法,本文详细讨论了其编译码方法,比较了两种快速哈达马变换和经典一阶Reed-Muller码的译码算法,并指出3GPP协议设计中的成功和不足之处,同时通过仿真测试验证了其纠错能力.

| Abstract: | Reed -Muller code is applied to TFCI coding in 3GPP,but the decoding algorithm is not concretely explained in the technical report.Hence,it is deduced in detail in this paper,and two FHT(Fast Hadamard Transformation) methods are compared,what is more,some excellence and inadequacies of 3GPP protocol design are pointed out.In addition,the TFCI coding meets the test of computer simulation. |
