Following user feedback regarding the challenging behavior of the multiband configuration, we are working to optimize the setup. We have identified that the current sampling rate restricts the observation bandwidth, limiting the visibility of wideband spectral regrowth. We are currently addressing this limitation to improve linearization performance.
Latest changes:
DUT Change (14/01/2026) We have replaced the DUT to a single-input LMBA provided by Politecnico di Torino. This change is already active for experiments. Please note that, due to this configuration, the shaping function is now bypassed. For full details, please refer to the Access and Scoring details section.
Frequency shift (26/01/2026) Center frequency adjusted to 3.7 GHz (previously 3.5 GHz) for improved linearity performance.

The returned MATLAB structure contains a field named "RX.error", which provides feedback regarding the transmission status. The server validates the input signals before processing; if any criteria are not met, the specific reason for rejection is detailed here: Rejected signal: RX.error = 1 "TX signals bad size" (wrong number of rows) RX.error = 2 "TX signals bad size" (wrong number of columns) RX.error = 3 "TX includes NaN" RX.error = 4 "TX signals modulus peak >2" RX.error = 5 "TX signals PAPR <7" Accepted Signal: RX.error = 0 "Everything in TX is ok" RX.error = 0.5 "TX signals modulus peak >1 (but <=2)" (There will be hardware clipping) |
