Instructions for BASK Simulation (with AWGN + Rayleigh)
Note:
Use the input fields to enter the SNR (in dB), number of multi-paths, excess delay (in ms), bit rate (in bps), and the symbol duration (in ms)
Step 1:
Click
'Generate BASK Message'
to generate the input BASK modulated signal
Step 2 & 3:
Click
'Generate Multi-path for Rayleigh'
and
'ADD AWGN Noise'
to simulate fading and add noise
Step 4:
Click
'LTI Output'
to generate the output after convolution with the channel
Step 5:
Click
'Plot BER vs SNR'
to compare BER with and without Rayleigh fading
