This paper presents a possible utilization of Two-Dimensional Complete Complentary Codes (2D OCCC) in radar technologies. The aim is to evaluate the ambiguity function and cross-ambiguity function of phase modulated signals based on the second family of 2D OCCC. Signal is generated by modulation technique known as Orthogonal Frequency Division Multiplexing(More)
The aim of the study was to find the diurnal changes in the EEG alpha-activity in patients with endogenous depressions. Both morning and evening EEG records were characterized by the transition of modal value of leading rhythm into the lower frequency band (9-10 Hz versus 10-11 Hz in healthy people). The spectral power of alpha-rhythm was higher, especially(More)
The group of liquidators of Chernobyl Nuclear Power Plant accident (n=170) with nonpsychotic mental disorders of exogenic-organic origin was studied. Patients were stratified into five groups on the basis of dominating symptoms in different stages of disorders: group 1 included patients with the prevalence of asthenic symptoms (n=104); group 2 - with the(More)
Eighty-two patients with depression with suicidal tendencies, 82 patients without these tendencies and 150 healthy people have been studied. An attempt has been made to reveal a correlation of results obtained in calculating the entropy and information saturation of EEG with signs of dysontogenesis in patients with depression with- or without suicidal(More)
