Compiler/IWR6843: IWR6843 pplcount capon BF algorithm matrix inverse question

user4542591

Part Number: IWR6843

Tool/software: TI C/C++ Compiler

Hi,

We design a board with IWR6843 chip, 3 transmitting antennas and 4 receiving antennas, forming 12 virtual channels, we want to run the ppcount demo program on the board, in the example ，the capon algorithm, need to compute the inverse matrix of Rn , how to calculate 12*12 Rn's inverse matrix ? a high-speed algorithm

thanks!

Hi,

This should be done the same way the 8*8 matrix is calculated in the provided source code on TIREX.

See the source code here: C:\ti\mmwave_industrial_toolbox_4_0_0\labs\people_counting\68xx_people_counting\src\common\modules\DoA\CaponBF\src
Do you know which order the antennas are in so you can properly label your virtual signals?

Regards,

Justin
