Multipath_Simulation

Using Python to simulate multipath fading channel

Channel power delay profile

Tap Power(dB) Delay(τi)
0 0 0 ns
1 -3 20 ns
2 -6 80 ns
3 -8 120 ns
  • (a) Please list the power ratio of 4 taps in linear scale
Tap Power(dB) Power(Linear) Power(Normalize) Delay(τi)
0 0 1 0.5233 0 ns
1 -3 0.5012 0.2623 20 ns
2 -6 0.2512 0.1315 80 ns
3 -8 0.1585 0.0829 120 ns
