Comparison of the distributed wireless communication systems characteristics with soft and hard decisions
Abstract
The efficiency of using soft assessment for transmission over a distributed wireless sensor network is considered. According to the simulation results, it was determined that the proposed transmission method has a tangible gain in terms of the probability of bit error, in contrast to the traditional use of hard assessment for transmission over a wireless channel with Rayleigh fading.
