Here are the outputs for constellation diagrams where we can see the quality of the signal. The graph obtained on the right is referred to the graph obtained before channel modeling and the graph on the left is obtained after the channel modeling. It is a 64 Quadrature Amplitude Modulation (QAM) scheme before equalization (on the right) and after equalization (on the left), as the signal is receiver at the receiver end under the multi path feature reflex and all types of distortion can be seen before the channel modeling.
After channel modeling we can obtain a much organized 64 QAM modulation. We can change the bandwidth and calculate what other parameters or values can be observed.
