Abstract

Methods and apparatus for voice and data interlacing in a system having a shared antenna. In one embodiment, a voice and data communication system has a shared antenna for transmitting and receiving information in time slots, wherein the antenna can only be used for transmit or receive at a given time. The system determines timing requirements for data transmission and reception and interrupts data transmission for transmission of speech in selected intervals while meeting the data transmission timing and throughput requirements. The speech can be manipulated to fit with the selected intervals, to preserve the intelligibility of the manipulated speech.

Claims

1. A method, comprising:

a voice and data communication system having a shared antenna for transmitting and receiving information in time slots, wherein the antenna can only be used for transmit or receive at a given time,

determining timing requirements for data transmission and reception;

interrupting data transmission for transmission of speech in selected intervals while meeting the data transmission timing and throughput requirements;

manipulating the speech to fit with the selected intervals, to preserve the intelligibility of the manipulated speech.

2. The method according to claim 1, further including compressing the duration of the speech.

3. The method according to claim 1, further including limiting data interruption to a predetermined duration.

4. The method according to claim 1, further including employing independent receivers or transmitters.

5. The method according to claim 1, further including employing shared receivers and/or transmitters.

6. The method according to claim 1, further including employing separate antennas.

7. The method according to claim 1, further including limiting downlink voice interruption to a predetermined amount.

8. The method according to claim 1, including sensing the presence of speech to determine what segments of the audio input may be discarded without degrading intelligibility.

9. A system, comprising:

an antenna;

a voice and data communication system sharing the antenna for transmitting and receiving information in time slots, wherein the antenna can only be used for transmit or receive at a given time;

a data/voice timing control module to determine timing requirements for data transmission and reception and to interrupt data transmission for transmission of speech in selected intervals while meeting the data transmission timing and throughput requirements; and

a speech analysis and control module to manipulate the speech to fit with the selected intervals, to preserve the intelligibility of the manipulated speech.

10. The system according to claim 9, wherein the manipulated speech is compressed.

11. The system according to claim 9, wherein the data interruption is limited to a predetermined duration.

12. The system according to claim 9, further including independent receivers and/or transmitters.

13. The system according to claim 9, further including shared receivers and/or transmitters.

14. The system according to claim 9, further including separate antennas.

15. The system according to claim 9, wherein the data is source and sinked by a navigation system.

16. The system according to claim 9, further including a data encoder and a data decoder for the data.

17. The system according to claim 9, further including a transmit/receive switch coupled to the antenna.

18. A system, comprising:

an antenna;

a speech source, a speech sink, a data source, and a data sink;

a transmit/receive/switch coupled to the antenna;

a speech analysis and control module coupled to the speech source;

a data/voice timing control module coupled between the speech analysis and control module and the transmit/receive/switch;

a transmit switch coupled to the data/voice timing control module, the speech analysis and control module, and a RF transmit module, which is coupled to the transmit/receive/switch;

a speech demodulator coupled to the speech sink;

a RF receive module coupled to the speech demodulator, a data decoder, and a time division control module, which is coupled to the data/voice timing control module;

a data encoder coupled to the data source, the time division control module, and data/voice timing control module, wherein the data decoder is coupled to the data sink.
