DoA X440 (main) Flowgraphs

Simulation Flowgraphs

• run_MUSIC_lin_array_simulation.grc: Execute this flowgraph to see a simulation setup of two-target tracking using MUSIC algorithm with an ideal uniform linear array.
• run_RootMUSIC_lin_array_simulation.grc: Execute this flowgraph to see a simulation setup of two-target tracking using Root-MUSIC algorithm with an ideal uniform linear array.
• run_calib_lin_array_simulation.grc: Execute this flowgraph to see a simulation setup involving the calibration of a non-ideal uniform linear array.
• run_MUSIC_calib_lin_array_simulation.grc: Execute this flowgraph to see a simulation setup of two-target tracking using MUSIC algorithm with a calibrated uniform linear array. It is required that run_calib_lin_array_simulation.grc is run first which saves a config file to be used by this flowgraph.
• run_RootMUSIC_calib_lin_array_simulation.grc: Execute this flowgraph to see a simulation setup of two-target tracking using Root-MUSIC algorithm with a calibrated uniform linear array. It is required that run_calib_lin_array_simulation.grc is run first which saves a config file to be used by this flowgraph.

Flowgraphs to Run Experiments with an X440

• run_DoA_transmitter.grc: Run this flowgraph to transmit a tone.
• estimate_constant_phase_offsets_and_save.grc: The first flowgraph to be run at the host PC in order to store the constant repeatable relative phase offsets in a config file. Refer to the wiki page or the whitepaper for more details on the calibration setup.
• view_op_with_corrected_phase_offsets.grc: Run this flowgraph to view the phase-corrected receive streams.
• calculate_phase_sync_accuracy.grc: Run this flowgraph to store the phase misalignment values post-correction in a config file.
• run_MUSIC_lin_array.grc: Execute this flowgraph to track one target transmitter using MUSIC algorithm with an uncalibrated uniform linear array.
• run_RootMUSIC_lin_array.grc: Execute this flowgraph to track one target transmitter using Root-MUSIC algorithm with an uncalibrated uniform linear array.
• calibrate_lin_array.grc: Run this flowgraph to calibrate a uniform linear array.
• run_MUSIC_calib_lin_array.grc: Run this flowgraph to track one target transmitter using MUSIC algorithm with a calibrated uniform linear array.
• run_RootMUSIC_calib_lin_array.grc: Run this flowgraph to track one target transmitter using Root-MUSIC algorithm with a calibrated uniform linear array.
