一、什么是空间调制在航空导航设备中 ,常会碰到“空间调制”这个概念 ,笔者刚接触到这个词时 ,也很奇怪 ,因为这是一个教科书中未提及的概念。实际上 ,“空间调制”并非是什么新的调制方式 ,只是因为调制的实现方法特别 ,调制是通过“空间”而非“电路”完成的 ,因此得名为“? First, what is space modulation In the aviation navigation equipment, often encounter the concept of “space modulation”, the author just came into contact with the word, is also very strange, because this is a concept not mentioned in the textbook. In fact, “space modulation” is not a new modulation method, simply because the modulation is implemented in a special way. The modulation is done through “space” rather than “circuitry”, hence the name “?”
