Construction of nested pattern matrix with large girth for PDMA systems

Abstract In this letter, a new method is proposed to construct the pattern matrix (PM) with both nested structure and large girth for pattern division multiple access (PDMA) system. The proposed method contains two steps. Firstly, by performing the Kronecker product on a cycle‐free base‐PM with over...
