Bit-rate-halving algorithm for PCM-encoded speech using a new bidimensional data compression scheme |
Abstract | ||
---|---|---|
The paper present an original numerical algorithm for reducing by a factor of two (32 Kbits/ sec) the bit rate of telephone speech already digitized in standard PCM. At the end of the line (i.e. expensive media) an inverse algorithm resynthesizes a PCM signal which preserves a high telephone quality. This bit-rate compression algorithm is thus essentially "transparent" to PCM transmissions and therefore finds immediate applications for increasing carrier capacity. In particular when used in connection with speech interpolation techniques [1] it enables a fourfold increase in the number of channels per carrier. |
