摘要
提出和实现了一种智能天线系统的模拟权值乘法器。这种乘法器将智能天线阵接收到的基带信号与模拟权值进行相乘,实现了智能天线的波束形成。其处理速度快,无量化误差,无需数/模和模/数转换,无需存储空间等外部设备,硬件完全由乘法器芯片和运放芯片组成,模拟电路简单,实现和调试方便。仿真和实验的对比结果表明,提出的模拟权值乘法器具有较强的可行性和可靠性。
An analog multiplier of complex weights in smart antenna system is proposed and realized.The multiplier has achieved beam-forming of smart antenna by multiplying the base-band signals and analog complex weights.This multiplier has high processing speed,has no A/D,D/A conversion,no quantification error,no memory space and other peripherals,whose hardware is composed of multiplier and amplifier chips.It has simple analog circuit and is convenient for implementation and debugging.The comparison of simulation and experimental result indicates that the multiplier proposed in the paper is of fairly high feasibility and reliability.
