Abstract
In recent days there is a need of wireless communication systems with greater standards.Orthogonal frequency-division multiplexing (OFDM) meritoriously mitigates inter symbol interference (ISI) present in the wirelesscommunication channels. As this undesired ICI degrades the performance of the communicationsystem. In this paper, we put our effort to investigatethe working scenario of OFDM system can perform when a signal is transmitted over an Additive white Gaussian noise (AWGN) channel using BPSK, QPSK, and 8QAM modulation schemes.In this paper, we studied and analyzed the various pulse shaping filters along with FIR and evaluated the performance ofthese pulse shaping filters The performance of OFDM system with uncoded and Coded pulse shaping filters are also evaluated and results reveal that the coded SQRC OFDM improve the overall performance of the system in terms of BER.
