circle, and so on, until the last element, that corresponds to the outermost circle. Element values must be multiples of four andsum(M)must be a power of two. The modulation order is the total number of points in the signal constellation and equals the sum of the vector elements,sum(M...
amplitude shift keying 英文amplitude shift keying 中文【计】 振幅键控
幅度键控(ASK)技术可通过结合乘法器和开关电路来运作。核心原理是利用载波的通断来传输数字信息。当数字信号为1时，载波被激活，使得信道上存在载波；而当信号为0时，载波被关闭，信道上无载波传输。接收端根据载波的有无，能够解析出原始的1和0信号。在ASK的特定形式，即二进制幅度键控(OOK)中，载波...
