Quadrature Amplitude Modulation (QAM) is a modulation scheme that conveys data by changing the amplitude of two carrier waves, which are out of phase with each other by 90 degrees. This method allows for the transmission of multiple bits per symbol, enhancing bandwidth efficiency, which is crucial in terahertz communication systems that seek to maximize data rates and minimize interference.
