A simple and effective quadrature phase shift keying (QPSK) signal design for a given correlation matrix is presented. The method exploits the correlation properties generated by memoryless nonlinear transformation of a Gaussian process. The correlation matrix of the designed QPSK signal is compared to the given matrix and good approximation is achieved.
