Presently, Orthogonal Frequency Division Multiplexing (OFDM) has been widely used as modulation technique for broadband wireless communication system. In this paper, OFDM simulation model has designed using MATLAB. The performance of OFDM system was investigated for several type of modulation schemes, i.e BPSK, QPSK, 16-QAM and 64- QAM. The physical layer performance on the basis of bit error rate (BER), signal to noise ration (SNR), power spectral density (PSD) and error probability were measured to compare the performance of system for each modulation scheme.
