Abstract
The next generation wireless communication system requires a higher standard in order to provide the customers with high quality of services they demanded. Orthogonal Frequency Division Multiplexing (OFDM) is an attractive modulation method and is a strong candidate for the modulation technique of future wireless systems which can be implemented easily. In this paper an effort is made to analyze how well an OFDM system will perform when transmitted over an Additive White Gaussian Noise (AWGN) channel in terms of Bit Error Rate (BER), it has also been observed that pulse shaping the channels present in an OFDM system promises to improve the overall performance of the system in terms of the BER of the received signals, different window function like Rectangular, Blackman, Gaussian, Hamming, Hanning and Kaiser and some of the self modified pulse shapes have been used to study the BER performance due to any one of the pulse shapes.
