Abstract
In this paper, we analyze balanced cycles of quasi-cyclic low-density parity-check (QC-LDPC) codes. We show the structure of balanced cycles and their necessary and sufficient existence conditions. Furthermore, we determine the minimal matrices of balanced cycle. Meanwhile we propose the property of B-girth in its mother matrix. Finally, we give the proof in theory.
