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 stri...
The present invention has an object to provide a matched filter circuit which is possible to synchronize a spreading code with an input signal. A matched filter according to the present invention samples input signal in response to three clocks from the first to the third shifted by a half cyc...
If you have a signal, x, then the matched filter's coefficients is given by time reverse of x, i.e., x(end:-1:1). If your signal is complex, you also need to to use complex conjugate. You can then use it just as an FIR filter. For example,...
Matched Filter Py This simple project features a Python implementation of a matched filter for signal detection in the domain of frequency. A matched filter is a signal processing filter used to detect the presence of a specific known signal (or pattern) in a noisy signal. It is called a "...
I am trying to create matched filter output vs Range. I created time spaced vector using linspace command. The sampling frequency is 1.25 GHz. I am trying to find Range using R=ct/2. The code is as follows u_filt=matched_filter(u_rx,h); Mag= abs((abs(u_filt)).*2); c=3e8;...
