摘要: Transmitters and receivers in multiple description coding systems use correlating decorrelating transforms to generate process descriptions of elements an input signal. The include groups transform coefficients that permit recovery inexact facsimile the signal if some are lost or corrupted during transmission. Noiseless implementations described allow be quantized with different quantizing resolutions. Implementations using Fast Hadamard Transform reduce resources needed perform transforms.
