Abstract
A method for creating cyclic permutation matrices P (), with an arbitrary size Z×Z set by a parameter Z5 and which are used to create one or more LDPC related matrices in OFDMA systems, comprising: defining an integer value Z; creating an initial matrix (); creating a matrix () by using cyclic shifts to each row; repeating stage 3, up to Z−2 times as required, thus creating up to Z−2 matrices: P(o) . . . P(Z−I); creating an additional stairs matrix P(st). A method for using cyclic per-mutation matrixes P (), with a fixed size Z×Z set by a parameter Z, and which are used to create one or more LDPC related matrices () in OFDMA systems, comprising: defining an integer value Z; storing in memory means an initial matrix () and its cyclic shifts permutations (), thus keeping memory means matrices: P(o) . . . P(Z−I); storing an additional stairs matrix P(st) (); using these matrices () to create LDPC related matrices () or LDPC operations.
