Abstract
In this study, a new pulse shaping method namely scale alpha is proposed for mitigating Inter-Carrier Interference (ICI) effect in Orthogonal Frequency-Division Multiplexing (OFDM) system. The suggested pulse shape is designed and simulated using MATLAB software. Results show that the new pulse shape has lower ICI power and better impulse response performance than Franks, raised cosine and double-jump pulses
Highlights
METHODOLOGYOrthogonal Frequency-Division Multiplexing (OFDM) is attractive because it can meet the demands of wireless communication technologies for fourthGeneration (4G)
It has been proven that high data speed transmission in mobile environment is achieved by OFDM system due to its ability to decompose a wideband frequency selective fading channel into several parallel narrow band flat fading channels (Assimonis et al, 2010; Palaivelan et al, 2012)
In Lin et al (2008), a pulse shaping function has been suggested to reduce the sensitivity of OFDM system to frequency offset which leads to Inter-Carrier Interference (ICI)
Summary
METHODOLOGYOrthogonal Frequency-Division Multiplexing (OFDM) is attractive because it can meet the demands of wireless communication technologies for fourthGeneration (4G). In Lin et al (2008), a pulse shaping function has been suggested to reduce the sensitivity of OFDM system to frequency offset which leads to ICI. A new scale alpha pulse shaping is suggested to alleviate ICI influence in OFDM system.
