TH8644B - Voice interpolation which was increased with reduced delay. - Google Patents

Abstract

In radio telephone networks, TDM provides a mechanism for inserting asymmetry in the paired frame switching connections. And multiplexing / sharing / band allocation The result is an increased alternating depth and a reduction in the delay to and from the line. The way to encode the traditional semi-rate speech.

Claims (8)

1. The transmitter unit consists of, connected to operate in a serial manner: a device for encoding speech from a user, a device for performing an encoded speech interpolation of others using a channel. It communicates logically, performs speech encodings as alternate pairs of coded speech frames, and devices for transmitting highly interpolated encoded speech frames. In sequence to the communication channel 2. The machine is accomplished as in claim 1. Here, each frame consists of a group of segments and an interpolation device is also operable to interpolate the coded speech. With others' coded speech into segments within each frame. 3. A complete machine, as in claim 2, herein an interpolation device is also provided. Actionable to insert encrypted speech with others' encrypted speech into segments. Delegates to segments within each frame. 4. A successful device, for example in claim No. 1 here, the communication channel will form a time slot. For repetitions in radio telephone systems with time division multiplexing. 5. The receiver unit consists of, connected to operate in a functional manner: a device for receiving frames of encoded speech that has been interpolated in a pair. Alternate with encoded other people's speech frames that share a logical communication channel for the recipient from the communication channel, a device for decoding frames of the recipient's encrypted speech from the frame Of other people's encrypted voices sharing a logical communication channel And a device to decode the recipient's encrypted speech frames for New sound simulation production 6. The machine is successful, for example in claim number 5. Here, the channel will form a time slot. For repetitions in radio telephone systems with time division multiplexing. 7. A radio transceiver consists of: a receiver that has, connected to operate in a serial manner: a device for receiving frames of encrypted speech interpolated in a manner. It is an alternate pair with frames of others, which are logically communicated with each other. For users from the communication channel, a device for decoding the encoded speech frames. Encrypted speech frames of others that use a logically common communication channel, and a device for decoding encrypted speech frames for the user to perform. Produces new audio simulations, and the transmission part which has, connected to operate in a serial manner: a device for encoding the voice of a user, a device for encoded by others using a transponder. communicate Logically, by making a pair of speech encoded alternating frames of the encoded speech, and a device for transmitting sequential frames of the encoded speech and the resulting Been interpolated into the communication channel 8. Methods for transmitting and receiving encoded speech include: receiving frames of encoded speech that have been interpolated in an alternate manner. With frames of others, which are used to communicate together logically For users from communication channels, decoding of encoded speech frames for users from other people's frames, which Utilizes a logical co-communication channel, and decoding of user-encoded speech frames for reproducing sound reproduction, and user speech encoding, encoded speech interpolation. Of others logically sharing the communication channel, where the speech is encoded as an alternate pair of encoded speech frames, and the encoded speech frames that have been inserted are transmitted. Insert at a continuous sequence to Communication channel
