The Filter Step of pre-DPD Crest Factor Reduction(CFR) with Filter Enabled Does Not Honor Non-zero Carrier Offset When the Number of Carriers Is Equal to 1

The filter step of CFR algorithm assumes that if the number of carriers is equal to one then the carrier is centered at 0Hz in the complex baseband waveform, and does not honor the user-configured or auto-detected carrier offset.

Workaround:

If the number of carriers is equal to one and carrier offset is non-zero then configure two carriers with the same carrier offset (0 Hz) and bandwidth.
