What is a QAM Signal Quadrature Amplitude Modulation (QAM) uses many different phases known as states: 16, 32, 64, and 256. Each state is defined by a specific amplitude and phase. This means the generation and detection of symbols is more complex than a simple phase or amplitude device. 1.docx - 1. Draw a 16-QAM constellation diagram with two ... 1.
