Abstract
Discrete Fourier transform (DFT) codes are used to provide robustness against packet losses in IP networks. First, the relationship between DFT codes and over-complete expansions using frames is established. It is shown that the message recovery by syndrome decoding of erasures and direct signal space projection from received samples are equivalent. The error performance analysis of DFT codes is used to develop packetization criteria in order to guarantee minimum reconstruction error
