Abstract :
A DVB-S2 compliant codec is implemented in both 130nm-8M and 90nm-7M low-leakage CMOS technologies. The system includes encoders and decoders for both low-density parity check (LDPC) codes and serially concatenated BCH codes. All requirements of the DVB-S2 standard are supported including code rates between 1/4 and 9/10, block sizes of either 16,200 bits or 64,800 bits, and four digital modulation options. The 130nm core design occupies 49.6mm2 and operates at 200MHz, while the 90nm core design occupies 15.8mm2 and operates at 300MHz.
