Dsp Implementation Of A Quadrature Phase Shift Keying Transmitter, Andrew Phoon

Theses : Honours

The aim of this project is to develop a DSP implementation of a QPSK transmitter. This transmitter is to process digital signals in real-time and modulate it with sinusoidal and cosinusoidal signals to produce the required QPSK waveform. This thesis is mainly divided into three sections. The first section deals with the theory of modulation. Phase shift keying, in particular binary phase shift keying, is explained in some detail, with references to the generation of quadrature phase shift keying. In the second section, a brief overview of the SIMULINK package from MATLAB is given, as simulations of ideal and nonideal …
