摘要

We consider the practical construction of successive refinement source codes for real sources and quadratic distortion. We propose a scheme based on convolutional codes and unitary transformations, efficiently implemented by FFT/IFFT and interleaving. This scheme offers performances comparable to the best known TCQ schemes and very fine granularity of rates. Then, we apply our scheme to adaptive source transmission over noisy channels with fixed spectral efficiency and to the broadcast approach for the BF-AWGN and broadcast Gaussian channel, extending the approach of Steiner and Shamai to the case of lossy transmission.
