Joint Source-Channel Coding for Coded Speech Transmission
N. Görtz · 2003
Coded speech transmission over noisy channels can be interpreted as a delayconstrained encoding/decoding problem for a set of continuous-amplitude signals; the latter are the parameters extracted from the actual speech signal by advanced source coding schemes. The optimization problem for the encoder/decoder-design is formulated and it is shown, that its direct solution is intractable in most relevant cases. Therefore, several approaches for the practical system design are discussed.
