Official bladeRF forum

. I read the vhdl code “iq_correction” at https://github.com/Nuand/bladeRF/blob/7 ... ection.vhd
But I can not understand :
[*] how the tan_table core works ?
[*] what is the equation to calculate the signal “phase_correction” and its meaning ?
[*] Is there any document for this vhdl code ?

The correction was adapted from what is described in the LMS7002M datasheet on page 8, Figure 16, under the section "IQ Phase Correction".

Hopefully this helps!
