QAMenkoodausme
QAMenkoodausme, also known as Quadrature Amplitude Modulation (QAM) encoding, is a digital modulation technique used in telecommunications and digital signal processing. It is a form of amplitude and phase modulation that combines two amplitude-modulated signals, which are out of phase with each other, to produce a single modulated signal. QAM is widely used in various communication systems, including digital television, cable modems, and wireless networks, due to its high spectral efficiency and ability to transmit multiple bits per symbol.
In QAM, the amplitude and phase of a carrier wave are varied to encode information. The basic
For example, in 16-QAM, there are 16 possible combinations of amplitude and phase, allowing each symbol to
QAM encoding is implemented using digital signal processing techniques, including modulation, demodulation, and error correction. The
Overall, QAM encoding is a versatile and efficient modulation technique that plays a crucial role in modern
