摘要
在3GPP(第三代合作项目)协议中,为了提高传输格式组合指示(TFCI)的可靠性,对其采取了基于Reed-Muller码的超码编码。与经典RM编码相比,不但增加了码距,提高了纠错能力,而且可以利用快速哈达玛变换(FHT)提高译码速度。文章对协议中的编译码算法进行了研究,并对其纠错能力进行了仿真。
In 3GPP,a coding method called supercode based on Reed-Muller has been adapted to improve the reliability of TFCI(transport format combination indicator).This coding technique can not only increase the minimum code distance,but also enhance the correction ability,and moreover,FHT(fast hadamard transformation) can be used to increase the decoding speed.In this paper the coding/decoding algorithm is presented,with simulation results verifying its performance.
