Presented paper concentrates on accidentally identified, specific method of mechanical vibration demodulation, radiated high-frequency signal of aircraft communication antenna, located directly on the aircraft. It describes the structure and solution of t... see more

Reflected background infrared radiation is an important contributor to the aircraft total infrared radiation. A reverse Monte Carlo ray tracing method to compute the infrared radiation signature of aircraft was introduced. The impact of atmospheric and gr... see more

Nonlinear partial differential equations are mostly renowned for depicting the underlying behavior of nonlinear phenomena relating to the nature of the real world. In this paper, we discuss analytic solutions of fractional-order nonlinear Schrodinger type... see more

This work proposes a solution to overcome the effect for one of the main drawbacks of these days’ wireless systems, where Multiple-Input Multiple-Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM) combinations has been used. High peak-to-aver... see more

It is proposed to use developed digital speech signal compression algorithm based on wavelet transform in the unmanned aerial vehicle voice control system. It is implemented the estimation of compression data ratio and bit rate depending on the parameters... see more

It is proposed to use developed digital speech signal compression algorithm based on wavelettransform using entropy arithmetic coding, which allows to achieve optimum results in the improvementof data compression while maintaining the intelligibility of s... see more

In ultrasonic testing it is very important to recognize the fault echoes buried in a noisy signal. The fault echo characterizes a flaw in the material. An important requirement on ultrasonic signal filtering is zero-time shift, because the position of ult... see more

In this paper, the problem of low probability of intercept (LPI)-based radar waveform design for distributed multiple-radar system (DMRS) is studied, which consists of multiple radars coexisting with a wireless communication system in the same frequency b... see more

In wireless communications, demand to provide high-speed data services with good performance raises new techniques to increase spectrum efficiency and improved signal quality due to frequency selective fading. OFDM is a multi-carrier technique can be used... see more
