Abstract: In wireless communication system, there exists a main demand for enhancing the data rates and to improve the system reliability. OFDM systems are widely used as modem of multicarrier transmission systems where the system has higher reliability and better bandwidth efficiency. In OFDM system, it is necessary to assess the performance of the system and Bit Error Rate provides the idle way in which the entire performance of a system including the transmitter, receiver and the medium between the two are assessed. In this way, BER enables the actual performance of the system operation to be tested instead of testing the component parts. In this paper, comparison of BER performance is carried out with two different transforms such ac FFT and DWT in which the DWT transform is performed with two different filters such as deubechies filter and Haar filter. Simulation are carried out to ensure the performance of the system and to obtain the optimum values of BER.
