    Abstract - (Show below) - (Hide below)

    Presents the results obtained from an internationally co-ordinated subjective evaluation conducted by four laboratories to estimate the performance in mobile-to-mobile connections of the GSM half, full, and enhanced full rate speech codecs (including the expected advantages of the Tandem Free Operation), in case of interoperability in the digital cellular telecommunications system.
