A generic architecture of CCSDS low density parity check decoder for near-earth applications |
Abstract | ||
|---|---|---|
Low Density Parity Check (LDPC) codes have recently been chosen in the CCSDS standard for uses in near-earth applications. The specified code belongs to the class of Quasi-Cyclic LDPC codes which provide very high data rates and high reliability. Even if these codes are suited to high data rate, the complexity of LDPC decoding is a real challenge for hardware engineers. This paper presents a generic architecture for a CCSDS LDPC decoder. This architecture uses the regularity and the parallelism of the code and a genericity based on an optimized storage of the data. Two FPGA implementations are proposed: the first one is low-cost oriented and the second one targets high-speed decoder. |
