Abstract :
A recently found "better than" raised-cosine pulse is employed in pulse-shaping orthogonal frequency-division multiplexing to reduce the inter-carrier interference due to frequency offset. The results show that new pulse outperforms the rectangular pulse and raised-cosine pulse in average inter-carrier interference power reduction.
