Irregular Low-Density Convolutional Codes Construction and Short Cycles Elimination Method
一种非规则卷积低密度校验码的构造和短环去除方法

A method for constructing Low-Density Convolutional (LDC) codes with degree distributions optimized for block Low-Density Parity-Check (LDPC) codes is presented. The encoding, decoding, and short cycles elimination methods are discussed in detail. Experimental results show that the LDC codes constructed with the optimized irregular degree distributions for block LDPC codes are superior to homogeneous (i.e., regular) LDC codes.
