Abstract
Orthogonal Frequency Division Multiplexing (OFDM) modulation using varied inputs,
code rates, modulation schemes and sub-carrier sizes over different fading and noisy
channels were developed and tested in this thesis. The different code rates were the 1
2 , 2
3
and 3
4 whilst the different modulation schemes were Binary Phase Shift Keying (BPSK),
Quadrature Phase Shift Keying (QPSK), 16-Quadrature Amplitude Modulation (16-
QAM) and 64-Quadrature Amplitude Modulation. The different size sub-carriers were
64, 256, 512, 1024, 2048, 4096 and 8192. The different channels were the Rayleigh fading
and the Rician fading channels. These aspects of the OFDM modulation system were
developed using Matlab 7.1 as code written program utilising the toolboxes available.
The simulator was setup to be able to mirror all current implementations of the technology.
Through the use of the simulator, a varied amount of system configurations were
tested. The system arrangement that was found to be the most resilient to noise was a
system using the three-quarter code rate, 64-QAM modulation and the 64 sub-carrier
size.
