摘　　要：在3GPP中,为了提高码距,TFCI采用了基于RM码的超码编码方式,这使得接收端的译码难度加大。利用快速哈达码变换,结合超码译码算法,给出TFCI译码算法,包括对双极性序列的变换以及去除掩码的处理过程。大量的仿真数据表明该方法具有实际应用价值。In order to improve code distance in 3GPP, TFCI (Transport Format Combination Indicator) adopted a method called supercode based on RM (Reed Muller), which made the decoding in receiving become difficult. Using FHT (Fast Hadamard Transformation) combined with supercode decoding, the decoding method for TFCI was given, including the transform of bipolarity serials and eliminate infection of the masks. A mass of simulation data shows this method has more actual values than traditional method.
