Project description:
You need to build charts in Mathcad:
- binary signal graph (from 0 and 1),
- to modulate it with DAM (discrete amplitude modulation), frequency w0 = 900 MHz.
- interference concentrated on the spectrum, in the form of harmonic oscillation with a frequency of wp 10% of f DAM signal.
The resulting signal graph is the sum of the modulating signal and interference.
- Discrete it for t. Kotelnikova (Upper frequency fv = w0 + wp).
- Consider the transmission over the OFDM communication channel (disparralization), it will be enough for 5 bits. Calculate the probability of error without concentrated interference and with its presence. I need the original mattacada file.
