Abstract: Orthogonal frequency division multiplexing(OFDM)has recently attracted vast research attention from both academia and industry and has become a part of new emerging standards for broadband wireless access. Synchronization at receiver end represents one of the most challenging issues and plays a major role in physical layer design.This paper presents design and implementation of a Channel estimation algorithm which successfully achieves minimization of Timing and Frequency offsets at receiver end. Also it has been synthesized and simulated on Virtex 6 device.
Keywords: Cyclic Prefix, Timing Offset, Intersymbol Interference (ISI), Channel estimator.
Scope of the Article: Frequency Selective Surface
