Increasing the reliability of wireless body area networks based on compressed sensing theory
Bibliographic record
Abstract
A Wireless Body Area network (WBAN) is a special purpose of Wireless Sensor Networks (WSNs) to connect various Biomedical Wireless Sensors (BWSs) located inside and outside of the human body to collect and transmit vital signals. The collected biomedical data send out via Gate Way (GW) to external databases at the hospitals and medical centers for diagnostic and therapeutic purposes. To increase the reliability of WBANs the power consumption and sampling-rate should be minimized in the Multipath Fading Channels (MFCs) between BWSs and GW. That is why an improving of MFCs as well as a low sampling-rate channel model is inevitably required for WBANs to expand WBANs to important applications such as Electronic Health (EH) and Mobile Health (MH). With this in mind, Compressed Sensing (CS) theory, as a new sampling procedure, is employed to MFCs in order to minimize power consumption and sampling-rate. The MFCs and the collaboration from an important platform for CS theory in order to provide lowpower and low sampling-rate WBANs expected to increase a lot in the future. Advance WBANs with MFCs based on CS theory will be able to deliver healthcare not only to patients in hospital and medical centers; but also in their homes and workplaces thus offering cost saving, and improving the quality of life. The simulation results confirm that detection probability of biomedical signals at GW increases by 25%, which will result in an increment in the received signal amplitude at GW. Our simulation results also illustrate that satisfying quality for Bit Error Rate (BER) can be achieved with CS.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
