Method and apparatus for data communication between a base station and a transponder
View Patent ↗In certain embodiments, a transponder comprises a transceiver configured to receive a forward link having a forward-link header comprising at least one symbol for configuring a setting of the transponder. The transponder may be configured to transmit a return link having a return-link header comprising information based on one or more characteristics of the transponder, and to receive a modified subsequent symbol of the forward-link header. The modified subsequent symbol of the forward link header generated by analyzing the return-link header to determine adjusted information for configuring the setting of the transponder and modifying the subsequent symbol of the forward-link header in accordance with the adjusted information for configuring the setting of the transponder.
1. A method comprising:
receiving at a transponder a forward link having a forward-link header comprising at least one symbol for configuring a setting of the transponder;
transmitting from the transponder a return link having a return-link header comprising information based on one or more characteristics of the transponder; and
receiving at the transponder a modified subsequent symbol of the forward-link header, the modified subsequent symbol of the forward link header generated by:
analyzing the return-link header to determine adjusted information for configuring the setting of the transponder;
modifying the subsequent symbol of the forward-link header in accordance with the adjusted information for configuring the setting of the transponder.
2. The method of claim 1 , wherein the one or more characteristics of the transponder comprise one or more of a resolution and a data transmission rate of the transponder.
3. The method of claim 1 , wherein the one or more characteristics of the transponder comprise an operating mode of the transponder.
4. The method of claim 1 , wherein the forward link specifies a reference time for one or more of defining a system clock and sets a data communication rate of the transponder.
5. The method of claim 1 , wherein analyzing the return-link header comprises determining clock information of the transponder based on a reference mark.
6. The method of claim 1 , wherein analyzing the return-link header comprises determining a time separation based on a reference mark.
7. The method of claim 1 , wherein the forward link specifies a reference time for modulation by the transponder.
8. A transponder comprising:
a transceiver configured to:
receive a forward link having a forward-link header comprising at least one symbol for configuring a setting of the transponder;
transmit a return link having a return-link header comprising information based on one or more characteristics of the transponder; and
receive a modified subsequent symbol of the forward-link header, the modified subsequent symbol of the forward link header generated by:
analyzing the return-link header to determine adjusted information for configuring the setting of the transponder;
modifying the subsequent symbol of the forward-link header in accordance with the adjusted information for configuring the setting of the transponder.
9. The transponder of claim 8 , wherein the one or more characteristics of the transponder comprise one or more of a resolution and a data transmission rate of the transponder.
10. The transponder of claim 8 , wherein the one or more characteristics of the transponder comprise an operating mode of the transponder.
11. The transponder of claim 8 , wherein the forward link specifies a reference time for one or more of defining a system clock and sets a data communication rate of the transponder.
12. The transponder of claim 8 , wherein analyzing the return-link header comprises determining clock information of the transponder based on a reference mark.
13. The transponder of claim 8 , wherein analyzing the return-link header comprises determining a time separation based on a reference mark.
14. A circuit configured to:
receive at a transponder a forward link having a forward-link header comprising at least one symbol for configuring a setting of the transponder;
transmit from the transponder a return link having a return-link header comprising information based on one or more characteristics of the transponder; and
receive at the transponder a modified subsequent symbol of the forward-link header, the modified subsequent symbol of the forward link header generated by:
analyzing the return-link header to determine adjusted information for configuring the setting of the transponder;
modifying the subsequent symbol of the forward-link header in accordance with the adjusted information for configuring the setting of the transponder.
15. The circuit of claim 14 , wherein the one or more characteristics of the transponder comprise one or more of a resolution and a data transmission rate of the transponder.
16. The circuit of claim 14 , wherein the one or more characteristics of the transponder comprise an operating mode of the transponder.
17. The circuit of claim 14 , wherein the forward link specifies a reference time for one or more of defining a system clock and sets a data communication rate of the transponder.
18. The circuit of claim 14 , wherein analyzing the return-link header comprises determining clock information of the transponder based on a reference mark.
19. The circuit of claim 14 , wherein analyzing the return-link header comprises determining a time separation based on a reference mark.
