| 20100136902 | Signal Power Summation Using Satellite Transponders Having Orthogonal Polarizations - A method for communication includes transmitting first and second copies of a signal toward first and second satellite transponders, respectively, so as to cause the first and second satellite transponders to transmit respective first and second downlink signals with mutually-orthogonal linear polarizations toward a coverage region. A correction is applied to at least one of the first and second copies before transmitting the first and second copies. The correction is selected so as to remove a frequency offset between the first and second downlink signals and cause the first and second downlink signals to have a constant phase offset in at least some of the coverage region. | 06-03-2010 |
