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 |
(b) Max excess delay
120 ns
(c) Mean excess delay
- (d) RMS excess delay
Channel
- (a) Channel impulse
- (b) Fourier transform
- (c) Channel frequency response
- (d) Subcarrier
Channel fading effect
- (a) TX_signal=[0 1 0 1 1 1]
- (b) Channel effect
- (C) NO ISI
CFO
- (a) TX_signal=[1 0 1 0 1 1 0 1]
- (b) After CFO
- (c) Complex plane
