The Systems using Orthogonal Frequency Division Multiplexing (OFDM) suffer with carrier frequency offset (CFO) results in inter carrier interference (ICI) due to which there will be large performance degradation. The impairment like CFO is caused due to mismatch of carrier frequency at the transmitter to local oscillator frequency at the receiver, multipath and Doppler shift. This paper presents a...
The Fourth generation (4G) wireless networks are expected to afford high data rate transmission of multimedia services such as wireless video, wireless Internet access and mobile computing. Orthogonal frequency division multiplexing (OFDM) is an effective technique for the future 4G communications because of its great immunity to impulse noise and intersymbol interference. Ultra wide band (UWB) wireless...
