Because of the rapid growth of Digital Communication in recent years, the need for high speed data transmission is increased. Orthogonal Frequency Division Multiplexing (OFDM) technique is suitable for high speed communication because of its resistance to ISI (Inter Symbol Interference) and it utilizes the bandwidth efficiently. DSSS-OFDM is a combination of OFDM and DSSS techniques suitable for design of multi-user system and robust against channel impairments. This paper compares Bit Error Rate (BER) performance of simulink based DSSS-OFDM model for different modulation technique.
