Abstract
Hardware aspects of infrastructured based (i.e., fixed) relay station design with focus on digital baseband processing in OFDM(A) based systems are investigated. A novel architecture for the digital baseband processor for fixed relay stations is proposed to minimize the relay complexity and the implementation cost. Two methods of signal forwarding -Amplify and Forward (AF) and -Decode and Forward (DF) are developed and implemented on FPGA, exploiting parallel processing and a pipelined system architecture. In contrast to common heuristical conclusions existing in the literature, we conclude that the AF based implementation introduces significant hardware complexity resulting from high memory usage. On the other hand, the DF implementation requires higher clocking frequencies, making it more power-consuming as comapred to AF-based relaying.

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
