Analysis of random signal energy detection under the influence of uncorrelated noise is implemented. The aim is to gain the signal to noise ratio in processing systemoutput. A comparison of proposed system with known and optimal systems is implemented. The dependencies of correct detection probability ofsignal to noise ratio were obtainedwith fixed false alarm probability. The proposed method allows to increase the average rate of improvement of signal-to-noise ratio in 5 times in comparison with the known system.

Key words: correlationmatrix, eigenvalues, energy detection, Karhunen–Loewe transform.
