We demonstrate a technique of using artificial neural networks trained with parameters derived from asynchronous diagrams for optical performance monitoring of quadrature phase-shift-keying (QPSK) ...

(2) Take, , values which are discrete values, and the related carrier phase, and an orthogonal vector corresponding to the same phase in the constellation diagram. It can be seen from Equation (2) ...

We propose a new full rate space-time block code for a three transmit antenna system that is orthogonal when using a special modulation scheme, called "triple QPSK". This space-time block code ...
