摘要
文中在现有传输格式组合指示(TFCI)的译码算法基础上,提出了基于3GPP业务速率和最大先验概率构造权重因子矩阵F的算法,并给出了其(16,5)TFCI译码的数学模型,初始化F矩阵以及基于时间统计的F(t)矩阵的计算方法,最后,在AWGN信道环境下比较了与原算法的误码率仿真图。
This paper proposes an improved practical TFCI decoding algorithm based on combination of FHT & Super Code Decoding and service rate & test case specified in 3GPP. Then it gives the mathematic model and the method for calculating F(0) &F(t), which is the initial gain factor in decoding. Finally, the simulation graphs of original and improved algorithms in downlink are provided
