Error Probability of OFDM Systems Impaired by Carrier Frequency Offset in Frequency Selective Rayleigh Fading Channels
— Orthogonal Frequency Division Multiplexing (OFDM) is sensitive to Carrier Frequency Offset (CFO), which destroys the orthogonality and causes Inter-Carrier Interference (ICI). ...

Narrowband Interference Mitigation in Turbo-Coded OFDM Systems
— A method for the mitigation of the effect of narrowband interference (NBI) on the turbo decoder in OFDM systems is proposed. The presence of NBI leads to a contaminated Gaussia...

Joint Reduction of Peak-to-Average Power Ratio and Out-of-Band Power in OFDM Systems
—The high peak-to-average power ratio is a major drawback of OFDM systems. Many PAPR reduction techniques have been proposed in the literature, among them a method that uses a su...

Blind channel shortening in OFDM system using nulltones and cyclic prefix
This paper considers the problem of blind channel shortening in OFDM systems. Standard OFDM systems use guard interval (GI) in form of cyclic prefix (CP) and nulltones (NT) redun...
