Hi all,Suppose I have an input signal \( x[n] \) of length \( N \), an FIR filter \( h[n] \) of length \( M \), and a window function \( w[n] \) of length \( N...

I am using the WLAN Tool Box of #Matlab V2107b. A term named CSI for each data subcarrier is defined as CSI(i) = H(i) X conj(H(i)) + N(i)H(i) = channel estimate...

## Visualizing the spectrum of a 433 MHz433 MHz signal in MATLAB

Started by 1 year ago●12 replies●latest reply 1 year ago●272 viewsI recorded a 433 MHz IQ signal with a SDR dongle as a .wav file and when I read it in #MATLAB, I see the following:This is the code:<code>[y,Fs] = audioread('HDSDR_SHORT_433920kHz_RF.wav',[5000000...

figure; plot(rcosfir(.2, 3, 12, 1/9600, 'sqrt') - rcosfir(.2, 3, 12, 1, 'sqrt'))The difference is negligible. Why does the 'T' parameter (symbol period) seem to...
