代码说明:

该项目建设的QC LDPC码的长度短没有周长4和周长6该计划提出了构建LDPC码的短长度周长8的方法。首先,我们设计3子矩阵与我们的方案给予不同的换挡功能,然后将它们组合成一个矩阵,根据我们的方法,最后,扩大矩阵成所需的奇偶校验检查矩阵使用单位矩阵和单位矩阵的循环移位矩阵。模拟结果在AWGN信道中显示其可以通过来自于该校验矩阵用于编码随机的信息比特的生成矩阵来获得的代码为随机LDPC码的一样好

    说明:  TFBSS是一种基于短时傅里叶时频分析的盲源分离算法,算法基于卷积混合。处理非平稳源信号。(TFBSS performs Blind Source Separation of (over)determined multiplicative mixtures of non-stationary real valued sources. TFBSS is based on the joint-diagonalization of whitened and noise-compensated Spatial Time-Frequency Distribution (STFD) matrices of the observations, corresponding to single auto-terms positions, as described in: C. Févotte and C. Doncarli. "Two contributions to blind source separation using time-frequency distributions", IEEE Signal Processing Letters, 2004. IEEE Signal Processing Letters, vol. 11, no. 3, Mar. 2004. pdf and A. Holobar, C. Févotte, C. Doncarli, and D. Zazula. "Single autoterms selection for blind source separation in time-frequency plane". In Proc. 11th EUSIPCO, Toulouse, France, 2002 (Special Session on Source Separation). pdf )
