Description

Pi/4 D-QPSK (Pi/4 shift Differential-Quadrature Phase Shift Keying) is a four level modulation scheme first proposed by Baker in 1962 and is currently the focus of intensive research. The scheme is currently implemented in the American Digital Cellular Japanese Handy Phone and the European TETRA systems.The aim of this undergraduate project was to implement a Pi/4 Shift D-QPSK baseband modula
