How to change QPSK data rate to 10kbps?

Hi JG,

There's a coupe of things to check here first:

• Check the sample time of the inputs and outputs of each IP to make sure they make sense in relation to the decimation/interpolation stages.
• Make sure you have changed the value of Rb and R_CIC in both the AXI_QPSK_Tx.slx and the axi_qpsk_rx_dec.slx files.

Try those out and, if they don't work, I'll have another look.

Hi,
I would like to change the bitrate to 10 Mbps, If I change the Rb = 10000000(from 1000) what should I use for the R_CIC value?
Is there a formula for different bit rates?

We are on the way toward over 10Msps=20Mbps and now, we are struggling with 3.2Mbps.
qpsk_tx seems to have no problem.
How to determine K factors for loop filters in qpsk_rx_tsync block?
I modified the block, changed the fixed values to variables and pulled them out so that I can change their values from Python.
