What is it about?
Real Gaussian Random Variables (RV's) are mapped into Quadrature Phase Shift Keying (QPSK) signals to design waveforms with specified auto- and cross- correlation properties and achieve a desired transmit beampattern.

Why is it important?
1) The beampattern design and waveform design problems are solved jointly 2) Once the transmit covariance matrix R is found, easily generated Gaussian RV are mapped into QPSK signals to construct the waveforms. 3) No iterative methods are needed 4) The generated signals have finite alphabets
Perspectives
This work was an extension of my supervisor's paper (http://ieeexplore.ieee.org/document/5962371/) where Gaussian RV are mapped into BPSK signals. We wanted to study how the relationship between the correlation of Gaussian RV's and Finite RV's changes when varying the mapping function.
