Viewing a QAM Signal on a Constellation Diagram. A very common way to transmit wireless data is to use quadrature amplitude modulation (QAM). This method uses two amplitude modulated signals, combined into a single channel at the same carrier frequency to increase the symbol transmission rate.

constellation diagrams 100 errors are calculated and then draw constellation diagrams between in-phase and quadrature-phase component. It is then shown that more disperse constellation diagram serves more fading at lower SNR. When we increase the value of SNR, constellations are less dispersed and BER reduced.

QAM stands for Quadrature Amplitude Modulation. It is digital modulation technique. This modulation technique is a combination of both Amplitude and phase modulation techniques. QAM is better than QPSK in terms of data carrying capacity. QAM takes benefit from the concept that two signal frequencies; one shifted by 90 degree with respect to the other can be transmitted on the same …
