Abstract

In this paper, the Improved Modified Bartlett-Hanning (IMBH) window family is used in an OFDM system to reduce the ICI. It is found that the IMBH pulse shape gives better results than the PMSP, ISP, BTRC, RC, Bartlett and rectangular pulse shapes in terms of both ICI and BER. The optimization of SIR in terms of window parameters has also been obtained. This analysis provides a better insight to control ICI or BER with proposed pulse shape. The IMBH pulse shapes give an improvement of 2---3 dB in ICI with different frequency offsets and roll-off factors. Similarly, with proposed pulse shapes the BER level can be obtained at lower SNR of approximately 5 dB. Therefore, the IMBH pulse shapes outperform other reported pulse shapes in both the dimensions, i.e., ICI and BER.
