摘要
针对π/4 QPSK(正交相移键控)调制器与QPSK进行了软件仿真比较,实验表明,π/4QPSK具有较高的频谱效率。通过硬件电路实现了π/4 QPSK调制器并用软件仿真对其进行了比较验证,结果证明了硬件实现的可行性及正确性,可用于移动通信实验及程控交换机中。
A simulated comparison is made between π/4 QPSK and QPSK. The computer simulations demonstrate that π/4 QPSK has higher frequency spectrum efficiency. In addition, hardware realization was carried out and compared with software simulation. Simulations proved the validity and feasibility of this design, which can be used in mobile communication experiment and programmed control of switching equipment.
