M-ary Phase Shift Keying Modulator block





This M-PSK modulator block computes the values of In phase/Quadrature (I/Q) components from integer values given in input. The phase is computed with the equation :


where u is the input integer value and M is the number of states defined with the dialogue parameter 'Number of states'. The values of outputs are given by :

y_{1}&=&cos\left(\varphi\right) \\

For example, for 4 and 8 PSK modulations, this bloc gives the following constellation diagrams :
