Improving of the Command Data Radio Link Stability to Interfering Factors

Abstract

. Analysis of the command data radio link’s in communication channel with multipath and the Doppler shift is made. The radio link is based on IEEE 802.15.4a standard CSS profile. It is shown the radio link possesses a high stability, when functioning in communication channel with the multipath and increased stability to the Doppler shift compared with the phase-shift keyed signal. For example the velocity of network point with a speed up to 300 km/h requires increase in the signal-noise ratio on 0,1 dB with a bit error probability 10 − 4 .
