Abstract: 

The problem of ultrawideband chaotic radio pulse propagation through the media within living organisms is considered in this article. This area gains relevance due to the increase of wireless communications applications in medicine, especially in diagnostics. It is important to research in advance the circumstances of radio signal propagation and their influence upon different wireless communication systems. In this work, the first experiments on measurement of the radio signal attenuation within living organisms for chaotic ultrawideband radio pulses occupying 3–5 GHz frequency domain are considered. Direct chaotic ultrawideband transceiver modules were used as transmitter and receiver. Cuvette filled with an aqueous solution of sucrose that provides electromagnetic characteristics of a living organism was used during the experimental research of a pulse attenuation rate. Signal amplitude on the output of logarithmic detector was measured in order to estimate path loss of the signal. The experiments were conducted when the cuvette was empty and filled with sucrose solution. Besides, different ways of antenna isolation from fluid were considered. Dependencies between path loss and the distance between transceiver antennas were obtained for the cases mentioned above. These results were further used to calculate signal attenuation rate within the medium. Based on the values of transmitter radiated power and receiver sensitivity one can make an estimation of the maximum transmission distance within the human body. These results were used to estimate the possibility of using ultrawideband chaotic signals of this frequency range for data transmission within living organisms.
