本文讨论采用择大判决模型的单脉冲PPK体制的抗干扰性能。计算该模型的误字率和通信效率、并与门限型判决模型和二进制传输系统作了比较。结果表明,择大判决始终优于门限判决。它能进一步降低PPK体制的误字率、或在一定容错概率下进一步提高PPK体制的能量效率。

This article discusses the anti-jamming performance of a one-shot PPK system using the maxi- mum decision model. The error rate and communication efficiency of the model were calculated and compared with the threshold-based decision model and binary transmission system. The results show that the decision of choice is always better than the threshold decision. It can further reduce the error rate of the PPK system, or further improve the energy efficiency of the PPK system with a certain probability of fault tolerance.
