CCS/AWR1843: TX Phase Coding

Part Number: AWR1843

Tool/software: Code Composer Studio

hello, i want to achieve the TX Phase coding.For example,All the Tx Transmitter the signal at the same time.TX1 for the Code Type1,TX2 for the Code Type2,TX3 for the Code Type3.How to config the Chirp or Profile??

thanks.

  • Hi,

    If you are planning to experiment with Phase Shifter on AWR1843 I recommend you first perform raw data capture using mmWave Studio and AWR1843BOOST+DCA1000 EVM. You can develop your own matlab or python code to post process the data or you can use the matlab integrated in mmWave Studio.

    Evaluating this feature with raw data capture will provide much more flexibility than implementing directly this feature using target code.

    In order to perform raw datat evaluation you will need following Hardware

    1) AWR1843BOOST EVM

    2) DCA1000 EVM

    In order to perform raw data evaluation you will need following software

    1) MMWAVE STUDIO

    Regarding Target Code:

    We have a demo available that shows how phase shifters are used to implement beamsteering.

    Please see Beamsteering TI Design and Demo that runs on AWR1843BOOST.

    The associated demo sw can be found in the Automotive Toolbox on the TI Resource Explorer "lab0011_mrr_beamsteering"

    This demo shows

    • how to configure different phases for each TX for a full frame
    • all TX are enabled at the same time

    I hope this helps

    thank you
