Abstract
An approach for minimizing variation in transmit power of synchronized signals that are destined to a satellite is disclosed. A gateway station system for communicating with a communication satellite includes a multiple signal sources which generate the synchronized signals. The gateway station system utilizes a control logic that is coupled to the signal sources. The control logic operates to offset selectively transmission times of a portion of the synchronized signals according to a predetermined distribution and an offset period. The predetermined distribution specifies about half the number of the synchronized signals are to be offset. The offset period is half a symbol period. The terminals within the satellite communication system has a receiver that receives the synchronized signal from the communication satellite. Each of the terminals also includes an offset-determination logic that is coupled to the receiver and determines whether the synchronized signals are offset based upon a received assignment message. The assignment message has a control flag field that indicates whether the received signal is offset.
