Abstract:
1. A method for determining attenuation settings across carriers in a return link from a user terminal to a gateway terminal via a satellite in a satellite communications system, the method comprising: determining a first attenuation setting for a first carrier of the carriers in the return link, the first attenuation setting based at least in part on a first signal quality metric value of a first message previously sent on the first carrier; determining a second attenuation setting for a second carrier of the carriers in the return link, the second attenuation setting based at least in part on a second signal quality metric value of a second message previously sent on the second carrier, the first attenuation setting being different than the second attenuation setting, the first carrier being different than the second carrier, and the carriers in the return link including the first carrier, the second carrier, and additional carriers; and computing a respective attenuation setting for each of the additional carriers in the return link not including the first carrier and the second carrier based at least in part on the first attenuation setting and the second attenuation setting.
