Hi,

My customer is checking the code of TXBF demo in C:\ti\mmwave_studio_03_00_00_14\mmWaveStudio\MatlabExamples\4chip_cascade_TxBF_example. They found in \PostProc\BeamSteerPhaseCalc.m, it uses different way for even and odd TX antenna. Would you pls kindly explain why?

Hello Chris,

Please give me some time to consult with the concerned team internally.

Regards,

Ishita

Hello Chris,

Sorry for the delay.

The odd and even TX antenna are treated differently to compensate for the phase quantization error of the 6 bit phase shifter.
