This paper contains study and comparative analysis of OFDM-IDMA system using BPSK technique in Simulink environment. Orthogonal frequency division multiplexing technique reduces long delay spread due to low data rate of subcarriers and due to which Inter Symbol Interference (ISI) is eliminated. Also the orthogonality of subcarriers reduces Inter Carrier Interference (ICI).Interleaver division multiple access (IDMA) layer are used to randomize the data so that the effect of channel noise does not corrupt the data serially. The main objective of this papers to analysis the performance of the OFDM-IDMA system on the basis of Bit Error Rate (BER). This simulation was done in MATLAB/Simulink and results are exported with the help of bertool.
