ICI Self – Cancellation for FFT-OFDM System
Orthogonal frequency division multiplexing (OFDM) is the projected modulation of choice for fourth-generation broadband multimedia wireless systems. OFDM based wireless systems are spectrally efficient but they are vulnerable to Inter carrier interference (ICI). The rapid variation of the channel can induce ICI. ICI will significantly increase the difficulty of OFDM channel estimation. ICI due ...
متن کاملPilot-Aided ICI Self-Cancellation Scheme for OFDM Systems
In this paper, a novel pilot-aided inter-carrier interference (ICI) self-cancellation scheme is proposed for use in orthogonal frequency division multiplexing (OFDM) systems. The proposed scheme maps both modulated data symbols and pre-defined pilot symbols onto nonneighboring sub-carriers with weighting coefficients of +1 and -1. With the aid of pilot symbols, a more accurate estimation of fre...
متن کاملA Survey of ICI Self-Cancellation Techniques for OFDM Systems
Inter-carrier Interference (ICI) is a severe problem in orthogonal frequency division multiplexing (OFDM) systems. Any offset between the subcarrier frequencies of the transmitter and receiver ruins the orthogonality of OFDM subcarriers and introduces ICI to an OFDM system. There are various methods to mitigate the effects of ICI. In this paper various ICI self-cancellation (ICI-SC) techniques ...

© 2014 Kyung-Hwa Kim and Bangwon Seo 537 http://dx.doi.org/10.4218/etrij.14.0113.0747 In this paper, we present a new inter-carrier interference (ICI) self-cancellation scheme — namely, ISC scheme — for orthogonal frequency-division multiplexing systems to reduce the ICI generated from phase noise (PHN) and residual frequency offset (RFO). The proposed scheme comprises a new ICI cancellation ma...
متن کاملA Technique for Ici Cancellation Using Bayesian Probability and Parallel Cancellation (bpici)
In past decade, the detection and mitigation of Intercarrier interference (ICI) in MIMO-OFDM system has been studied by various researchers due to the presence of frequency offset. Literature presents several works for ICI cancellation as like, iterative receivers, parallel cancellation (PIC) and so on. Among various techniques, researchers have put much concentration on PIC detectors which is ...
