Abstract
A concurrent dual-band low intermediate frequency receiver, which is based on the multiport correlator, is proposed in this letter. Only one single local oscillator signal is used to demodulate the dual-band RF signals at the same time, which greatly reduce the receiver complexity. The system configuration, output power theory, as well as the power spectrum are analyzed in detail, and then an appropriate baseband signal recovery theory is put forward. Finally, a concurrent dual-band six-port receiver is tested under the long-term evolution signals with 3- and 5-MHz bandwidths. The measured error vector magnitudes are all lower than 2%, which verify the proposed system structure and the signal recovery theory.

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
