摘要

提出了一种新的基于四维天线阵的方向相关QPSK调制技术。其基本原理是利用不同位置的天线元件来传输同相和正交基带信号。通过这种方式，QPSK调制在空间中形成并依赖于方向。仿真结果表明，该技术具有较窄的误码率波束宽度，适用于物理层安全无线通信。

A QPSK modulation scheme based on four dimensional antenna arrays

A novel direction-dependent QPSK modulation technique based on four dimensional (4D) antenna arrays is proposed in this paper. The basic principle is that the antenna elements of different positions are used to transmit the in-phase and quadrature baseband signals. In this way, the QPSK modulation is formed in space and dependent on directions. Simulated results show that this technique offers a much narrower BER beam width and is suitable for physical-layer secure wireless communication.
