  Abstract

Currently, OFDM (Orthogonal Frequency Division Multiplexing) is used in mobile communications. OFDM has high OOB (Out Of Band) power characteristics. Therefore, there is a restriction on the efficient use of frequency resources. Much research has been conducted to solve this problem, for example, FBMC and UFMC. In this paper, we use the windowing method. However, if windowing is applied to OFDM symbols, information is damaged. Therefore, the end of the symbol is extended by the windowing length to prevent the information from being damaged. It also introduces the window based on cosine function, which shows better performance than the existing window function, and introduces how to apply it. We compare the performance of proposed window function with Hann window having the best performance among the existing Window functions. We confirmed the performance improvement of 2dB and confirmed the improvement of 4dB by applying different method.
