Abstract The paper presents the substantiation of algorithm for forming the structure and technique for message transmission in unidirectional radio communication systems. The proposed algorithm is intended for use before the beginning of signal transmission for implementing the single-use reliable transmission technique with delayed acknowledgement, but with the possibility of forecasting the interference conditions at the receiving point. The algorithm stages are also discussed and analyzed. The first stage involves the search of the threshold quantity of correctly received symbols of message, the quantity of its blocks and the length of code sequences, which ensure the attaining of required probability of erroneous reception (malfunctioning). The first stage of the algorithm is proposed implying the need to follow a specific order of operations that include gradual increase of the threshold, gradual rise of the quantity of message blocks, and gradual increase of the length of code sequences. The second stage involves the calculation of the structure of discrete messages and algorithm of their transmission that ensure the required probability of correct reception. It is proposed to execute this stage in a specific order that includes gradual increase of the repetition multiplicity of message transmission, gradual rise of the quantity of frequencies for parallel transmission of message, and gradual increase of the length of code sequences. It has been proved that precisely such order of algorithm execution ensures the best indicators regarding the required time and the optimization of the computational complexity (in terms of the number of iterations) in providing the required transmission validity in unidirectional transmission radio systems.

在单向无线电系统中形成消息传递结构和阶段的算法

摘要 本文介绍了形成单向无线电通信系统中消息传输的结构和技术的算法的具体化。所提出的算法旨在在信号传输开始之前使用,以实现具有延迟确认的一次性可靠传输技术,但具有预测接收点干扰状况的可能性。还讨论和分析了算法阶段。第一阶段包括对消息正确接收符号的阈值数量、其块的数量和码序列长度的搜索,以确保获得所需的错误接收(故障)概率。提出算法的第一阶段意味着需要遵循特定的操作顺序,包括逐渐增加阈值、逐渐增加消息块数量和逐渐增加代码序列长度。第二阶段涉及计算离散消息的结构和它们的传输算法,以确保正确接收所需的概率。建议按照特定的顺序执行该阶段,包括逐渐增加消息传输的重复次数,逐渐增加消息并行传输的频率数量,以及逐渐增加码序列的长度。
