Abstract :
A CODEC fully compliant to DVB-S2 broadcast standards is implemented in both 0.13 μm 8M and 90nm 7M low-leakage CMOS technologies. The system includes encoders and decoders for both LDPC codes and serially concatenated BCH codes. This CODEC outperforms the DVB-S2 error performance requirements by up to 0.1dB. The 0.13 μm design occupies 49.6mm2 and operates at 200MHz, while the 90nm design occupies 15.8mm2 and operates at 300MHz.
