Abstract: A system, method, and apparatus for integrated resource planning for satellite systems are disclosed. The method involves obtaining user communication demand for at least one region. The method further involves generating a beam map comprising at least one beam for each of the regions according to the user communication demand. Also, the method involves generating at least one configuration profile for the satellite system by using the beam map. Additionally, the method involves performing a performance analysis by comparing: the user communication demand versus one of the configuration profiles, the user communication demand versus actual communication demand, one of the configuration profiles versus the actual communication demand, and/or one of the configuration profiles versus another one of the configuration profiles.

Abstract: Devices and methods are disclosed for reducing power control cushion of a user terminal configured to communicate with a satellite and a gateway station. The present invention provides a power control algorithm implemented in a user terminal that is designed to operate in a satellite communication system. The power control algorithm can recursively calculate a returnlink power to reduce a power control cushion so that an extra link margin is available to the satellite communication system. The present invention also provides a source coding technique that provides an accurate feedback signal for the user terminal. The average metric of input signal frames is coded in a sequence of bits that are carried by contiguous output signal frames.

Abstract: A method of encoding information bits of a communication signal for a communication system (10) is provided. The method includes decomposing the communication signal having a corresponding M1-ary modulation constellation into a M2-ary constellation, and a M3-ary constellation to generate one or more symbols Si. The one or more symbols Si are mapped using a bit-to-symbol table to generate an encoded communication signal. Decoding methods are also provided for uncoded modulation and trellis coded modulation (TCM). A transmitter (20) comprising an encoder (12) for performing TCM that is capable of transmitting a fractional number of information bits per transmitted symbol is also provided.
