This paper presents the conventional and multiband Orthogonal Frequency Division Multiplexing (OFDM) simulation software named Signal Modulation Simulator (SiMiSIM). A simulation system was built with a Graphical User Interface (GUI) to provide a more user friendly interface than contemporary or command line interfaces. Three basic frequency modulation techniques were made available in SiMiSIM: Binary Phase Shift Keying (BPSK), Quadrature Phase-Shift Keying (QPSK) and Quadrature Amplitude Modulation (QAM). Each of the signals had to face Forward Error Correction (FEC) encoder to enhance the signal robustness at the receiver end. The simulation was able to simulate Bit Error Rate (BER) and Power Spectral Density (PSD) for research purposes as well as educational purposes.
