摘要： A low-cost, low-power, low-complexity, small, high-reliability, robust, seamless satellite communication network is described. The network performs encoding of a user signal at the customer premises to enable routing of the user signal to an appropriate destination beam at the satellite requiring low power user signal processing. Routing information is embedded at the periphery of the network CPE's rather than at the satellite. Embedding the routing information in this way greatly reduces on-board switching complexity and increases signal to interference ratio for the user.

摘要： A mechanism that enables a gateway to dynamically determine which of two transmission signal polarizations is best received by a wireless communication device having a nominally linear antenna. A first pilot and second pilot signals, having different polarizations and orthogonally encoded, are transmitted to the communication device. The communication device determines the relative or absolute signal strengths of the first and second pilot signals and transmits this information to the gateway. The gateway then selects the polarization having the strongest associated signal strength to transmit content-bearing signals to the communication device. Alternatively, the communication device may also determine the phase difference between the first and second pilot signals and transmit this information to the gateway. The gateway can then transmit content-bearing signals using a proportional amount of signal power on each the first and second polarizations and use the proper phasing to approximate the polarization orientation of the communication device.
