Quadrature amplitude modulation - Wikipedia

64QAM or 64 Level Quadrature Amplitude Modulation is a digital modulation technique used as a basic building block within the OFDM Orthogonal Frequency Division Multiplexing waveform used in Cellular Telephony LTE & 5G networks (Ref.1). QAM modulation encodes information into the different … See more One way to construct a QAM signal is to combine various amplitudes of two vectors I & Q formed by I = Acos(wct) and Q = Bsin(wct). This construction method is shown in Figure 1. … See more Figure 2 shows the Scicos Model used to construct a 64QAM modulator. Random data is generated by the Random Integer Generator which outputs an integer from 0 – (M-1) where M = 2^N.

Web64QAM is a basic building block of OFDM Orthogonal Frequency Division Multiplexing used in many Telecommunication Systems such as DRM, LTE & 5G Cellular. As in many digital modulation schemes, the constellation diagram is useful for QAM. In QAM, the constellation points are usually arranged in a square grid with equal vertical and horizontal spacing, although other configurations are possible (e.g. a hexagonal or triangular grid). In digital telecommunications the data is usually binary, so the number of points in the grid is typically a power o…
