This block implements a carrier frequency offset model that can be used to simulate carrier frequency drift typically from mixer LO drift on either transmit or receive hardware.
A clipped gaussian random walk process is used.
Parameters
(R): Run-time adjustable
- Sample rate Hz (R)
- Sample rate of the input signal in Hz
- CFO standard deviation (Hz per sample) (R)
- Desired standard deviation of the random walk process every sample in Hz
- Max CFO bound Hz (R)
- Maximum carrier frequency deviation in Hz.
- Seed
- A random number generator seed for the noise source.
