Abstract
Wireless in-band backhaul, i.e. in-band distribution links (IDL) and inter-tower communications networks (ITCN) were previously proposed as key enabling technologies for the next-generation digital broadcasting systems, a.k.a. the Advanced Television Systems Committee (ATSC) 3.0 system. Both ITCN/IDL can be operated in the spectrum-efficient in-band full-duplex (IBFD) mode and the same frequency band is shared between the broadcast service signal and the ITCN/IDL signals. Integrating multi-input multi-output (MIMO) into ITCN/IDL transmission is desirable to increase the throughput and reduce the portion of the spectrum occupied by ITCN/IDL. Self-interference cancellation (SIC) in IBFD communications with the dual-polarization MIMO in ATSC 3.0 is investigated in this paper. A MIMO SIC was previously proposed by the authors which is capable to cancel both the co-polarization and cross-polarization self-interferences without requiring a dedicated training phase for the SIC filter weight estimation. Foregoing a dedicated training phase is more spectrum efficient and flexible in system design, however, it results in the presence of the remote signal of interest as an “intrinsic noise” in the SIC filter weight estimation. An iterative “intrinsic noise” cancellation scheme is proposed in this paper to further improve the MIMO SIC performance.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
