Review On Ici Reduction Techniques In Ofdm System
نویسنده
چکیده
Orthogonal frequency division multiplexing (OFDM) is a promising technique for the broadband wireless communication system. However, the inter-carrier-interference (ICI) produced by the phase noise of transceiver local oscillator is a serious problem. The variations in Time Offset (TO) can lead to inter-symbolinterference (ISI) in case of frequency selective channel. Literature survey of any research filed or subject is must required, before contributing in the research of that field. The literature review gives a detailed study of existing published material for clear understanding of that area. Therefore, this Paper presents a detailed literature survey of the area taken (i.e., OFDM). The study in this paper highlights different problems or issues of OFDM system like high PAPR, synchronization, and Inter-Carrier-Interference (ICI). This review also summarizes the methods available in the literature to overcome these problems.

Orthogonal frequency division multiplexing (OFDM) is one of the multi-carrier modulation (MCM) techniques that transmit signals through multiple carriers. These carriers (subcarriers) have different frequencies and they are orthogonal to each other. Orthogonal frequency division multiplexing techniques have been applied in both wired and wireless communications, such as the asymmetric digital s...
