QPSK Communications Systems

The main objective of this assignment was to design and analyse the performance of a Quadrature Phase Shift Keying (QPSK) Digital Communication System in MATLAB.

 

The system's performance was initially evaluated in the presence of noise, and then in the presence of a jammer.
