"This notebook walks you through how to implement $ x := L^T x $ where $ L $ is lower triangular. Vector $ y $ is not to be touched (and, indeed, not even passed into the routines). This is a little ...

Abstract: This study used the weight (3, 6) approximate lower triangular regular parity check matrix to implement the LDPC encoding on the 5641R FPGA of the Software Define Radio system developed by ...
