Research output: Patent

Abstract

There is disclosed a method of creating an LDPC code that is defined by a parity-check matrix H. The parity-check matrix H is derived from a (0,1)-geometry which is induced by a finite inversive space. This inversive space has an order q where every circle in the inversive space contains exactly q+1 points, q is preferably even, and most preferably equal to 2. Where the inversive space has a dimension n. Where the (0,1)-geometry is formed as a derived geometric structure based on pencils of degree m!
