Hierarchical block that combines Phase Noise Generator, IQ Imbalance Generator, Second Order Distortion, Third Order Distortion, IQ offset and frequency offset
Here is the flowgraph corresponding to the implementation (without the parameters)
Parameters
(R): Run-time adjustable
- Phase Noise Mag. (R)
- Magnitude given to the Phase Noise Generator. (Alpha is set to 0.01)
- IQ Mag. Imbalance (R)
- Magnitude parameter for the IQ Imbalance Generator.
- IQ Phase. Imbalance (R)
- Phase parameter for the IQ Imbalance Generator. (The mode is set to Receiver)
- Quadrature Offset (R)
- Offset added to the Q channel.
- Inphase Offset (R)
- Offset added to the I channel.
- Frequency Offset (R)
- Frequency offset to add.
- The signal source used for frequency offset is set to work at 1 sample per second. This probably need to be taken into account.
- Second Order Distortion (R)
- Parameter given to the Second Order Distortion block.
- Third Order Distortion (R)
- Parameter given to the Third Order Distortion block.
