AWR2243: AWR2243 Cascade SIMO Configuration

Part Number: AWR2243

We are working with the AWR2243 Cascade board Lua scripts that are provided with the mmwave studio generation 2. To perform a SIMO, we have been editing the following scripts: Cascade_Configuration_TestSource.lua (mostly this one) and Cascade_Capture.lua. We would like to know where the methods in these codes are defined such as ChirpConfig_mult. We would also like to know what exactly constitutes a SIMO configuration as opposed to a MIMO. Does a SIMO configuration mean that only the master device has a singular TX enabled and all 4 RX enabled while all the slaves have all of the TXs disabled with the 4 RX enabled? Or is there one TX enabled for each device with all of the RX enabled?

    Hi,

    The APIs such as "ChirpConfig_mult" are implemented in the mmwave studio tool.

    Usually SIMO refers to Singe Tx and Multiple Rx.

    Usually we don't use such a mode because it does not have any benefit.  We usually use either MIMO or Beamforming which enables all the TX at the same time. This is similar to SIMO but all TX are enabled

    thank you

    Hi,

    We understand that the APIs are implemented in mmwave studio tool and we know where to find the scripts where they are used. We want to see the functions/code so we can understand how and when they are used. Is there a document to show the code involved in the API?

    With SIMO, is it a single Tx for all devices on the cascade board or should each device on the board have a Tx enabled?

    Many thanks,

    Sarah

    Hi,

    Sorry for the delay.

    Unfortunately there is no additional documentation for the mmwave Studio APIs

    The cascade board is functionally equivalent to a sensor with the total number of Rx/Tx

    So, SIMO would be enabling a single TX

    thank you
