摘要

为了在下行蜂窝网络中实现安全通信，提出了毫米波(mmWave)移动宽带。毫米波传输采用带移相器的模拟波束形成。分析了时延容忍传输和时延限制传输两种不同传输模式下的保密吞吐量。研究了毫米波频率下大型天线阵列对保密吞吐量的影响。数值结果证实了我们的分析，并表明毫米波系统可以显著提高保密性。此外，研究表明，在大型天线阵列下，容忍延迟的传输模式可以在毫米波频率下实现每秒千兆比特的安全链路，并且在限制延迟的传输模式下可以消除保密中断的不利影响。

Secure communication in cellular networks: The benefits of millimeter wave mobile broadband

This paper proposes millimeter wave (mmWave) mobile broadband for achieving secure communication in downlink cellular network. Analog beamforming with phase shifters is adopted for the mmWave transmission. The secrecy throughput is analyzed based on two different transmission modes, namely delay-tolerant transmission and delay-limited transmission. The impact of large antenna arrays at the mmWave frequencies on the secrecy throughput is examined. Numerical results corroborate our analysis and show that mmWave systems can enable significant secrecy improvement. Moreover, it is indicated that with large antenna arrays, multi-gigabit per second secure link at the mmWave frequencies can be reached in the delay-tolerant transmission mode and the adverse effect of secrecy outage vanishes in the delay-limited transmission mode.
