Abstract
A system of satellite signal down conversion and reception comprises a low noise block down converter and a plurality of receivers. The low noise block down converter simultaneously and periodically sends a reference timing command to the plurality of receivers. Each of the plurality of receivers calibrates its timing based on the reference timing command to generate a plurality of data frames. Each of the data frames includes a plurality of time slots, and a time slot is designated to transmit data between the receiver and the low noise block down converter. Furthermore, each of the plurality of receivers uses a different time slot.
Claims18
A system of satellite signal down conversion and reception, comprising:
- a plurality of receivers;
- and
- a low noise block down converter simultaneously and periodically sending a reference timing command to the plurality of receivers, wherein each of the receivers calibrates its timing based on the reference timing command to generate a plurality of data frames and each of the data frames includes a plurality of time slots;
- wherein each of the plurality of receivers transmits data or issues request commands, through a designated one of the plurality of time slots in transmission channels of a time division multiple access bus, to the low noise block down converter, the plurality of receivers respectively uses a different time slot, the low noise block down converter generates reply data in response to the request command, and the reply data comprises a setting occupation check bit.
A signal transmission method for a system of satellite signal down conversion and reception, comprising the steps of:
- simultaneously and periodically sending a reference timing command from a low noise block down converter to a plurality of receivers;
- and
- calibrating the reference timing of the plurality of receivers based on the reference timing command to generate a plurality of data frames, wherein each of the data frame comprises a plurality of time slots and each of the plurality of receivers transmits data to the low noise block down converter through a designated one of the plurality of time slots, and the timing command or a reply message sent from the low noise block down converter further comprises a setting occupation check bit.
