A REVIEW ON CHANNEL ESTIMATION USING BP NEURAL NETWORK FOR OFDM

Digital watermarking is a term to describe inserting data invisibly within a host sound, image or video file in order to prove ownership. Over the past decade many watermarking techniques have been proposed to make this possible. Any such mark should still be detectable after common processing operations, including lossy file compression. Various audio watermarking techniques representative of this work will be implementing against many sound processing operations which may or may not remove the watermark. The individual strengths and weaknesses will be analysed. In proposed work, the algorithm should be able to add more data with less BER (Bit Error Rate).
