随着无线通信技术在铁路系统中迅猛发展和广泛应用，对通信系统装备的抗干扰能力提出更高更新的要求，因此必须研究有效的抗干扰技术以对付日益严重的干扰威胁。在粒子群算法中采用量子力学和经典力学的理论，将量子离散粒子群算法应用于多用户检测技术。在铁路无线通信系统中，可以提高铁路信道质量，降低数据通信误码率，解决列车与调度指挥中心之间的高数据通信中误码率高的问题，并且在抗多址干扰能力明显优于传统检测器。%With the rapid development of railway wireless communication, more rigorous requirements for anti-interference ability of the communication system devices are put forward. Therefore, it is necessary to study the effective anti-jamming technology to deal with the growing threat of interference. Quantum mechanics and classical mechanics are used in particle swarm optimization algorithm and quantum discrete particle swarm algorithm is applied to multi-user detection. In the wireless railway communication system, it improves the quality of the channel, reduce bit error rate, and solve the problem of high bit error rate in high data communication between the train and the dispatch command center, and proves superior to traditional detectors in terms of anti multiple access interference.
