XM radio satellite reception without degrading coverage in XM terrestrial markets
View Patent ↗A system is provided for enhancing coverage for a mobile satellite service, the system comprising a signal threshold comparator module for monitoring a predetermined threshold for a satellite service signal received on a first frequency band, a signal gain block operable to vary amplification of the satellite service signal received on a second frequency band in response to the threshold, and a satellite receiver for decoding the satellite service signal received on the first and second frequency bands.
1. A system for enhancing coverage for a mobile satellite service, the system comprising:
a signal threshold comparator module for monitoring a predetermined threshold for a satellite service signal received on a first frequency band, wherein the threshold is a predetermined bit error rate of the signal on the first frequency band;
a signal gain block operable to vary amplification of the satellite service signal received on a second frequency band in response to the monitoring, wherein the signal gain block increases amplification of the signal received on the second frequency band when a bit error rate of the signal received on the first frequency band exceeds the threshold, and otherwise decreases amplification of the signal received on the second frequency band; and
a satellite receiver for decoding the satellite service signal received on the first and second frequency bands.
2. The system of claim 1 wherein the mobile satellite service is a satellite radio service.
3. The system of claim 1 wherein the first frequency band comprises frequencies for receiving satellite radio signals from one or more terrestrial satellite repeaters.
4. The system of claim 1 wherein the second frequency band comprises frequencies for receiving satellite radio signals from one or more satellites.
5. The system of claim 1 wherein the threshold is a predetermined signal strength level of the satellite service signal received on the first frequency band.
6. A method for enhancing coverage for a mobile satellite service, the method comprising:
monitoring a predetermined threshold for a satellite service signal received on a first frequency band, wherein the threshold is a predetermined bit error rate of the signal on the first frequency band;
in response to the monitoring, varying amplification of the satellite service signal received on a second frequency band by increasing amplification of the signal received on the second frequency band when a bit error rate of the signal received on the first frequency band is greater than the threshold, and otherwise decreasing amplification of the signal received on the second frequency band; and
decoding the satellite service signal received on the first and second frequency bands.
7. The method of claim 6 wherein the mobile satellite service is a satellite radio service.
8. The method of claim 6 wherein the first frequency band comprises frequencies for receiving satellite radio signals from one or more terrestrial satellite repeaters.
9. The method of claim 6 wherein the second frequency band comprises frequencies for receiving satellite radio signals from one or more satellites.
10. The method of claim 6 wherein the threshold is a predetermined signal strength level of the satellite service signal received on the first frequency band.
11. A non-transitory computer readable medium having stored thereon computer executable instructions for enhancing coverage for a mobile satellite service, the instructions comprising:
monitoring a predetermined threshold for a satellite service signal received on a first frequency band, wherein the threshold is a predetermined bit error rate of the signal on the first frequency band;
in response to the monitoring, varying amplification of the satellite service signal received on a second frequency band by increasing amplification of the signal received on the second frequency band when a bit error rate of the signal received on the first frequency band is greater than the threshold, and otherwise decreasing amplification of the signal received on the second frequency band; and
decoding the satellite service signal received on the first and second frequency bands.
12. The non-transitory computer readable medium of claim 11 wherein the mobile satellite service is a satellite radio service.
13. The non-transitory computer readable medium of claim 11 wherein the first frequency band comprises frequencies for receiving satellite radio signals from one or more terrestrial satellite repeaters.
14. The non-transitory computer readable medium of claim 11 wherein the second frequency band comprises frequencies for receiving satellite radio signals from one or more satellites.
