16-Quadrature Amplitude Modulation
The 16QAM (Quadrature Amplitude Modulation) scheme is a modulation technique utilised in digital communication systems. It is a combination of both amplitude and phase modulation, allowing for the transmission of data over radio or cable. The '16' in 16QAM signifies that there are 16 different states or combinations of amplitude and phase changes that can be used to represent data. This enables the transmission of 4 bits per symbol, enhancing the data rate. However, the complexity of this scheme makes it more susceptible to noise and interference, requiring a higher signal-to-noise ratio for effective operation.
