Abstract

fetched live from OpenAlex

Location-awareness is expected to be one of the main services in 5G millimeter-wave (mmWave) communication systems. In mm-Wave, multiple-input multiple-output (MIMO) systems will be used, leading to the deployment of antenna arrays in both transmitter and receiver. Hardware components being used in transceiver are commonly modeled as linear filters; but practically, this linearity is not fully satisfied. Power amplifiers and filters applied in antennas mostly show nonlinear behavior, causing loss in spectral efficiency (SE) and signal quality. This non-linearity is referred to hardware impairments (HWIs). Under HWIs model at both the transmitter and receiver, 2D localization performance is examined. Towards that, we derive position and orientation error bounds and study the effect of HWIs on the derived bounds. The numerical results reveal that HWIs have a significant effect on localization and it causes more than 100% degradation in both the transmitter and receiver. Also, the rate of degradation stays the same for both position and orientation error bounds except for the oriented UE.

Full frame distilled prediction

Teacher imitation

Not 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.
