Abstract :
We propose a method to reduce the circuit size with demodulators for BS digital broadcasting and for terrestrial broadcasting by integrating them. Specifically, we propose an approach for integrating an FIR filter in a BS demodulator, and a carrier filter in a demodulator for terrestrial broadcasting. Experimental results have shown that the proposed approach reduces 17% of the circuit size compared with the sum of each filter.
