A method and computer program to configure feeds on a satellite ( ) to provide for redundant coverage when a satellite ( ) fails. Further, this method and computer program can enable the switching of feeds from commands from a ground station ( ) to activate certain feeds and deactivate other feeds when demand for service changes. In addition, this method and computer program allow for repositioning of satellites so that when one satellite fails another satellite may take over its area of coverage by switching active feeds without the need for placing another satellite in orbit.

A system and method for increasing the performance of a satellite communication system by using a multivariate analysis approach to optimize the pointing of the boresight of a satellite-mounted antenna. Optimizing the pointing of the boresight of the antenna minimizes sidelobe generation, and thus Co-Channel Interference (CCI) in geographic areas served by the system. By minimizing CCI, the overall system performance of the communication system is optimized. To optimize the pointing of the boresight of the antenna, the overall performance of the satellite communication system is determined, and the boresight of the antenna is iteratively repointed in the direction of increasing system performance until the optimized boresight pointing is determined. Alternatively, the frequency re-use plan of the satellite communication system may be analyzed to determine a high density cell region and the boresight may be pointed to the high density cell region.

A digital automatic level control system employs delay elements, which enable information about a signal parameter from the past, present and future to be processed to provide an optimal gain that can be used to level rapidly varying signals, such as bursty signals. As digital time samples of a signal are passed through first and second buffers, first and second accumulators maintain running sums that are related to the sum of the samples presently in the first and second buffers, respectively. The sums in the first and second accumulators represent information about the signal parameter for the future and the past, respectively. By choosing the maximum of these two values, the system can anticipate the beginning of a signal burst, and still have enough delay to compensate the end of a signal burst. In one embodiment of the invention, multiple channel signals can be leveled, either individually or in groups.

A method and apparatus are provided coding communications signals carried between transmitting and receiving stations and A data stream from a communications signal is encoded with an outer code to form an outer-coded data stream that is passed to an inner coder The inner coder applies an inner code and punctures the resulting coded data stream by deleting at least one bit from each symbol to achieve a desired data rate and coding level. The system offers multiple levels of puncturing to vary the coding level between heavy and light. The inner code may be a Nordstrom-Robinson code and the outer code may be a Reed-Solomon code.

A system and method is provided for efficient analog reconstruction of a digital signal to an intermediate frequency (IF). The digital signal can be a complex baseband digital signal that is sourced from a near perfect reconstruction filterbank (NPRFB). The output of the NPRFB, after some manipulation in the digital domain, is converted to the analog domain at IF. The IF analog signal can then be modulated with a high frequency RF signal or further mixed with a RF transmission frequency signal for RF transmission.

A filterbank system is provided for reordering subbands of a wideband digital signal. The filterbank system extracts the subbands from a wideband digital input signal into an even channel number group of even channel number subbands and an odd channel number group of odd channel number subbands. The separation of even and odd channel number subbands provides an even channel grouping with guard bands between the even channel number subbands and an odd channel number grouping with guard bands between the odd channel number subbands. The filterbank system then reorders the even channel number subbands and the odd channel number subbands. The reordered subbands are then combined by combining the reordered even channel number subbands and odd channel number subbands into a wideband digital output signal.

A frequency channel is assigned to each of a plurality of locations. A beam within the assigned channel and having a specified beam width is directed between a satellite and each location, and data is transmitted. A spread spectrum test signal is transmitted to the satellite, received, and processed, and a return test signal is transmitted from the satellite, and processed to determine the quality of operation of the antenna and associated electronics. A radio frequency signal having a first polarization is transmitted to the satellite, received, and processed to provide a first processed signal. The quality of the first processed signal is determined. If the quality is acceptable, the first processed signal is utilized. If the quality is not acceptable, the signal source is notified, and the radio frequency signal is retransmitted with a second polarization, received, processed, and utilized.

A communications system, a communications station, a method of controlling the power to transmitters in a communications station, and a storage medium storing instructions for controlling power to a communications satellite. The power consumed by each transmitter is determined, and desired power settings are determined. The power consumed is compared with the desired power settings. If the power settings are not proper, then it is determined whether the desired power is available. If so, then the power settings are adjusted. If not, then load priorities of the transmitters are determined, and if there is sufficient power to provide for the determined load priorities, the power settings are adjusted. The communications station includes variable gain amplifiers (---), to provide intermediate signals; high gain amplifiers (---) for amplifying the intermediate signals to output signals; monitoring power supplies (---) for determining the power provided by the high gain amplifiers, and a power profile processor () for adjusting the gain of the variable gain amplifiers.
