Discrete Fourier Transform (DFT) error recovery codes like Reed Solomon codes in the Finite Field are widely used in the communication systems. But the DFT codes in the real and complex fields of numbers are very unstable in the burst of error situations. This paper proposes to change the oversampling patterns in the encoder from the consecutive zero padding to sparse zero padding. It will also prove that the DFT codes based on this type of oversampling are decodable and stable in the case of burst of errors. The simulation results also show the robustness of these codes against quantization error and burst of errors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
