A New Approach for the Construction of Powerful LDPC Convolutional Codes
Christian Cardinal, Yucheng He, David Haccoun · 2008
A novel approach for the algebraic construction of low-density parity-check (LDPC) convolutional codes is presented. It is based on the orthogonality structures of the codes. The proposed code construction leads to a girth of at least 10 in the Tanner graph. The error performance of these codes compares favorably with the usual LDPC convolutional codes, especially at low signal-to-noise ratio range.
