Save And Load Dpd Coefficients From Last Transmission; Define The Frequency Region When Performing Dpd With Fh - Analog Devices ADRV9001 User Manual

Reference Manual ADRV9001
DIGITAL PREDISTORTION (DPD)
This parameter is critical, especially for wideband applications, due to the high sample rate. In narrowband applications, it is less critical. So, set
it to 0 unless there is a larger delay in the external loopback path.
Set these two configurations through TES, as shown in Figure 198.

SAVE AND LOAD DPD COEFFICIENTS FROM LAST TRANSMISSION

The ADRV9001 DPD also allows to save and load DPD coefficients from the last transmission. Therefore, the DPD can either start from scratch
(unity coefficients) or a set of known coefficients. This is a very useful option to reach convergence quickly under a similar transmit operation
condition. Use this feature as shown here in the TES.

DEFINE THE FREQUENCY REGION WHEN PERFORMING DPD WITH FH

Perform the DPD operation during FH. Define the seven frequency regions as shown here in the TES.
