BPS receiver

A BPS receiver comprising:

• a sampling process unit which samples a signal summing a first RF signal and a second RF signal of different frequency bands with time gap;
• a quantization process unit which generates a first stream signal and a second stream signal, a digital signal down-converted through respective time information in the signal summing the first RF signal and the second RF signal;
• and
• a signal process unit which performs FIR filtering with reference to phase shift for a respect frequency band of the first stream signal and the second stream signal, separates the first RF signal and the second RF signal based on a result of the performance,
• wherein the signal process unit comprises:
• a first interpolant unit and a second interpolant unit performs FIR filtering by inputting the first stream signal and the second stream signal;
• and
• a third interpolant unit performs FIR filtering by inputting the first stream signal and the second stream signal.
