Performance Enhancement of UFMC Systems using Kaiser Window Filter

초록

Universal Filtered Multi-Carrier (UFMC) is one of the strongest waveform candidates for the next-generation wireless communication system. In the UFMC system entire band is divided into sub-bands and a filter is applied in each sub-band. This filtering process reduces out-of-band (OoB) radiation as a result decrease inter-carrier interference (ICI). This paper use kaiser window instead of Dolph-Chebyshev filter which is used in conventional UFMC system. The simulation result shows that Kaiser Window UFMC (KW-UFMC) improves performance in bit error rate (BER), power spectral density (PSD), and peak-to-average power ratio (PAPR) compared to conventional UFMC system.
