Abstract:
OFDM is used to encode data on multiple subcarriers; its wide range of applications includes
implementation in 4G networks. OFDMA is the assignment of subcarriers used in OFDM to
multiple users. The goal of this project was to study the workings of OFDMA, by first
understanding the concept of OFDM; then using that understanding to implement the
modulation for multiple users on a MATLAB module. After the study of OFDM, an
algorithm was developed to cater for contention of use by multiple users. Once the MATLAB
module was perfected, it was converted to a C code which can be run on DSP Kit. The scope
of the project also allows for the study of further techniques in how OFDMA can be
optimized
