Web6 de jan. de 2024 · The hybrid scheme also subsumes prior coding methods such as rate-one separate source-channel coding and uncoded schemes for two-way lossy transmission, as well as the correlation-preserving coding scheme for (almost) lossless transmission. Moreover, we derive a distortion outer bound for the source-channel … WebLossy Source Coding Theorem Theorem 2.7.2: Let {X i} be a stationary, ergodic source, where X i is a real random variable a) for any n-dimensional variable rate block code (or vector quantizer) Q b) For any ε>0, no matter how small εis, there exists an n-dimensional fixed rate block code Q* for sufficiently large n such that ( ) if E[d(X , Q ...
