Mobile wideband speech communication (HD Voice) is more and more available in the past years, primarily in 3G networks. The specifics of mobile communication — even if it is packet-switched — is that received frames with residual bit errors after channel decoding must not necessarily be marked as lost, instead they may be marked as bad (bad frame indicator,(More)
Variable-length codes (VLCs) are widely used in media transmission. Compared to fixed-length codes (FLCs), VLCs can represent the same message with a lower bit rate, thus having a better compression performance. But inevitably, VLCs are very sensitive to transmission errors. In this work, based on the trellis representation for VLCs and the BCJR algorithm,(More)
