CFO Model

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.
