Comparative Study of ICI Cancellation Methods in OFDM System

Namrata Yadav, Santosh Kumar Gupta, Geetika Srivastava, Sachidanand Shukla


Now-a-days, wireless communication is increasingly in demand for high data rate applications. The orthogonal frequency division multiplexing (OFDM) is one of the digitalize modulation utilized in a wide area of communications framework. It is a successful modulation and multiplexing technique that is utilized in various systems like IEEE 802.11a, IEEE802.16e (or WiMAX), hiperlan/2, DAB, DVB, DSL. OFDM uses the multi sub-carriers within the single channel and these sub-carriers are closely spaced orthogonal signals, transferred in parallel scheme. OFDM is the way to slow down the symbol rate without slowing down the data rate.  However, there are some problems with OFDM like Carrier Frequency Offset (CFO), Bit error rate (BER) & Inter Carrier Interference (ICI). Due to the different carrier frequency offsets, orthogonality of sub-carriers is degraded and even the small change in carrier can lead to ICI. This paper focuses on the technique of improving the performance of OFDM for wireless communication by reducing the ICI caused by Carrier Frequency Offset (CFO). This paper delivers the number of wireless communication standards and numerous applications where OFDM systems are referred and can be used in the future techniques.
