Reliability analysis of digital communication systems with imperfect voters☆

In this paper, we consider the problem of achieving optimal redundancy for digital communication system, assuming that the failure of the unit (channel and voter) can take one of two forms. The reliability of the system is defined as the probability that the correct judgment will be made at the output of the system when entering the system. We derive general equation of system reliability and discuss optimization problem which maximizes system reliability.

Each voter can easily join his pocket, home, or community center via digital device. Many people feel that the current system is outdated, unreliable and unreliable. Why do not allow face-to-face voting and digital voting during the transition to full digitalization? Voting can be done quickly, easily, and conveniently rather than hindering the lives and responsibilities of voters.

Reliability analysis predicts the operational performance of the link or link system. Statistical models are used to predict the annual downtime, the percentage of unavailability, and the percentage of reliability. This analysis provides a critical verification that the selected link budget parameters are sufficient to support the intended communication. Microwave paths are usually designed for reliability of "Five Nine" or 99.999% reliability. This reliability corresponds to about 315.5 seconds of downtime per year. However, depending on the requirements of the system application, the required reliability may be higher or lower than 99.999%.
