| contents | <p><span>Most short-wave radio communication means use frequency modulation of the radio signal in a limited frequency band to transmit voice signals. Such signals have a sufficiently high spectral density, which makes it possible to detect and suppress the radio signal by means of electronic warfare. One of the methods for increasing the noise immunity of radio communication means is to expand the radio signal spectrum at the operating frequency of the transmitter.</span></p> <p><span>In modern telecommunication systems, various technologies for expanding the signal spectrum have been used when transmitting data over a microwave radio channel. In this case, the required speed of digital data transmission with the required quality is ensured by using a sufficiently wide radio channel bandwidth. Under the conditions of existing limitations on transmitter power, the required radio line range is ensured by adaptively changing the transmission duration, which allows to significantly increase the value of the radio signal base. However, the duration of real-time transmission of a speech signal is limited by the value of the voice signal sampling period. Therefore, the increase in the radio signal base in the short-wave range is possible through the use of broadband signals with a spectrum width that exceeds the width of the radio channel of existing narrow-band communication devices. When introducing broadband technologies in the short-wave range, it is important to check electromagnetic compatibility with existing narrow-band short-wave range devices. The paper proposes a method for determining the range of a broadband radio communication device and mathematical modeling of its compatibility with narrow-band devices at their spatial and temporal separation.</span></p> |
