Matched filter circuit |
摘要 |
A matched filter with reduced electric power consumption is disclosed. The matched filter circuit power consumption is reduced by stopping the electric power supply to an unnecessary circuit since input signal is partially sampled just after an acquisition. Since the spreading code is 1 bit data string, the input signal sampled and held is branched out into the signal groups "1" and "-1" by a multiplexer. The signals in each groups are added in parallel by a capacitive coupling, and the electric power is supplied in the circuit intermittently.
