Oversampled DFT codes have already been studied for erasure channels Me IP networks. We propose oversampled DCT transforms called DCT codes for erasure channels. We show that DCT codes offer more flexibility in design as compared to DFT codes and for some cases, lesser average mean square reconstruction error for erasures decoding. DCT codes have been studied before for error correction. In this article, we look at their suitability for signal reconstruction from erasures. We also propose methods to construct oversampled transforms from standard orthogonal transforms like Hadamard, sine transforms for robustness. to erasures.Read More
