Radio signals detection thresholds estimation for energy detection technique.

The estimation method for signal-to-noise ratio threshold values pertinent low-level signals detection is developed and employed. applicable original energy technique based upon distribution-free statistics computed using spectrum samples provided by measuring equipment. Estimated thresholds are determined equipment inherent noise fluctuations can be established in advance certain hardware settings sample lengths. For a typical analyzer model estimated sensitivity varied from +0,6 dB to –11 lengths ranged between 470 30 000 spectrums respectively. Experimental data confirmed equivalence of white (generated analog generator) broadcasted LTE cellular base stations). suggested independent signal's modulation, probability distribution features, intermittent or sporadic total duration allotment profile within acquisition period.
