摘要:
针对常规兵器遥测系统信道卷积编码参数依靠经验和非量化指标选择,而带来系统设计余量过大,造成资源浪费和系统最终可靠性性能不明确的问题,提出了考虑多径衰落的卷积编码参数确定的方法。该方法首先计算考虑多径衰落损耗的自由空间电波传播路径损耗;然后根据通讯距离方程计算系统实际增益值;接着算出信道编码增益的最小值;最后由编码增益,考虑设计余量后查表确定信道卷积编码的参数值。仿真结果表明:确定的卷积码型能够准确有效地提供常规兵器遥测系统所需的编码增益,避免了盲目选择参数时造成的系统资源浪费和系统有效性的降低。
Abstract:

The parameter determine method on convolutional coding,with considering the multi-path fading was proposed in this

paper,which aimed at reducing the waste of system resource caused by the lack of quantitative index and could also provide

reference for reliability improvement in the field of conventional weapon telemetry.In this paper,it was predicted and

computed that the radio wave propagation loss in the freedom space with considering the multi-path fading.Then,it was

calculated the practical system gain by communication range equation,and the minimum value of channel coding

gains.Considering the design margin and the minimum coding gain,it was determined that the value of channel coding parameters by consulting the relevant table.The simulation result showed that the computed convolution code type could provide the accurate and sufficient coding gain for conventional weapon telemetry system,and avoid system resource waste and validity reducing caused by blind parameter choice.
