| Summary: | The Quadrature Amplitude Modulation (QAM) is a digital modulation scheme that is widely used
in the communication system. The rotated QAM is a variation of QAM where the constellation is
rotated by an angle about the axis.
The focus of this project is to document the performance of the conventional and rotated QAM
schemes simulated under various fading channels such as the AWGN, Rayleigh fading and Rician
fading. The simulation will be done on MATLAB and the Bit Error Rate (BER) results will be
used for comparison between the theoretical and simulated results. The report will begin with the
theoretical background various digital modulation scheme and fading channels. Next the
simulation results and conclusion on the project. |
