Destination cooperation in interference channels
Bibliographic record
Abstract
Multiple Input Multiple Output (MIMO) techniques are used to exploit spatial diversity and to achieve high bit rates required for emerging multimedia applications. Cooperative communication can be used to achieve the diversity gains typical of MIMO without the need for multiple antennas on the consumer units. In this paper, we investigate the use of receiving node (destination) cooperation. We evaluate the performance of destination cooperation in an interference channel (DC-IC). We compare the performance of this system with the baseline 2-user orthogonal channel method. We demonstrate that the 2-user DC-IC outperforms the baseline technique by far. This is due to the cooperative communication. In the cooperative scheme, the receiver nodes in the first time slot, decode the received information from both sources while in the second time slot they cooperate. The scheme provides both diversity and coding gain. Using a typical scenario, we illustrate the efficiency of employing such technique with and without channel coding. However, the proposed technology can be applied to consumer mobile communication devices such as smart phones, tablets, etc...

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
