Abstract

It is proposed a method for increase of reliability of information transmission in wireless networks, functioning in conditions of influence of deliberate noise. The method is based on additional application of uncertainty factor in case of decision making in the turbo decoder in conditions of non-stationarity of the transmission channel. In a process of adaptive regulation of turbo code decoding iterations amount is modified for each data packet basing on dynamic calculation of uncertainty factor. Simulation results show increase of signal to noise ratio results in decoding iteration decrease, and information transmission reliability increase.
