Abstract:
The problem of ultrawideband (UWB) chaotic radio pulses propagation in the presence of a human body is investigated as well as application of these signals for wireless Body Sensor Networks (BSN) The measurements of the parameters were conducted with a help of UWB direct chaotic transceivers with bandwidth 3-5 GHz, developed by Kotelnikov Institute of Radio Engineering and Electronics of RAS and "NanoXaos". The results for the office environment are as follows: the path loss at a 1 m distance PL0=67.2 dB and path loss exponent γ=2.7 for CM3 channel when transceivers were placed in a line of sight (this result corresponds to the maximum range of 1.2 m between the transceivers); PL0=80.5 dB and path loss exponent γ=3.5 for CM3 channel when transceivers were placed not in a line of sight (this result corresponds to the maximum range of 0.4 m between the transceivers); PL0=49.3 dB and path loss exponent γ=1.5 for CM4 channel when transceivers were placed in a line of sight (this result corresponds to the maximum range of 23 m between the transceivers). Thus, the results of the conducted experiments (concerning maximum range) in CM4 channel meet the requirement for this channel model (5 m range). The obtained results illustrate that direct chaotic transceivers are capable of becoming a foundation for the new transceivers implementing IEEE 802.15.6 functionality for the use in WBAN.
