Abstract
This paper presents a real time programmable
irregular Low Density Parity Check (LDPC) Encoder
as specified in the IEEE P802.16E/D7 standard. The
encoder is programmable for frame sizes from 576 to
2304 and for five different code rates. H matrix is
efficiently generated and stored for a particular frame
size and code rate. The encoder is implemented on
SC140 Processor and different optimization
