    Speech/Data Discrimination in Communication Systems

    This paper proposes a discrimination algorithm, which discriminates speech and data on a multiplexed input signal. Commercial communication networks may use single voice band channel for transmission of both speech and data. Also, for optimum utilization of channel, the pauses in voice signal are being utilized. At receiver side the...
