摘要： A broadband multi-beam satellite radiocommunication system configured to implement a scheme for re-use of frequencies from a total band allocated to an uplink comprises a satellite with a multi-beam receive antenna that forms adjacent reception spots of a terrestrial coverage. Each reception spot consists of a central inner zone and a peripheral zone. Each central inner zone is a cellular pattern identical except for a scale factor to geographical cells wherein the principal frequency sub-bands of a bundle of separate or adjacent principal sub-bands are unitarily distributed and the combination of which is equal to a principal band, included in the total band.

摘要： A modulator generates a modulation signal from an input signal. A serial-parallel converter generates a subcarrier modulation signal from the modulation signal. An IFFT unit performs an inverse fast Fourier transformation on the subcarrier modulation signal, generating first data. A decomposer decomposes the first data into real data and imaginary data. An operator performs a predetermined operation using a predetermined threshold value, a boundary value and the real data, generating positive data and negative data. Another operator performs a similar operation on the imaginary data. A generator adds the positive data and negative data based on the real data, and adds the positive data and negative data based on the imaginary data, generating real operation data and imaginary operation data. A synthesizer synthesizes both operation data to generate a baseband signal. A transmitter generates a transmission signal from the baseband signal, and transmits it to another apparatus via an antenna.

摘要： It is possible to perform effective communication based on an A-SRS transmitted from a mobile station apparatus. A base station apparatus: notifies the mobile station apparatus of control information for setting, to the mobile station apparatus, whether to transmit a first sounding reference signal assigned in a physical uplink shared channel resource or to transmit a second sounding reference signal assigned in a resource different from the physical uplink shared channel resource; and notifies the mobile station apparatus of an uplink grant including an indication of transmission of a sounding reference signal. When receiving the indication of transmission of the sounding reference signal included in the uplink grant, the mobile station apparatus transmits the first sounding reference signal to the base station apparatus when the transmission of the first sounding reference signal is set by transmission control information, and transmits the second sounding reference signal to the base station apparatus when the transmission of the second sounding reference signal is set by the transmission control information.

摘要： An outgoing transmission carrier frequency at, for example, a remote terminal, may be adjusted based on a feature rate of an incoming transmission. The adjustment may compensate for error in the outgoing transmission carrier frequency. The incoming transmission may be from a satellite or hub, for example. The outgoing transmission may be the signal that is transmitted by an antenna, or the outgoing transmission may be converted to be at another carrier frequency such as a higher carrier frequency for ultimate transmission by an antenna. Also, a remote terminal may be synchronized to a satellite network with or without knowledge of the remote terminals' geographical location and with or without time stamps.

摘要： A communication system and a method of providing a feeder link to an earth orbiting satellite transponder having a mobile link illuminating spot beams with associated access channels, control channels and traffic channels for multiple user terminals (UTs) using the satellite transponder as the reference point to correct for dynamic frequency errors including the Doppler in the feeder link and in the mobile link caused by the satellite motion and the satellite translation error. A satellite access node (SAN) includes one or several radio frequency terminals (RFTs) and a satellite basestation subsystem (SBS). The RFT performs the center Doppler correction for each of the channels of the feeder link to the satellite transponder. The SBS corrects the feeder link residual Doppler and the satellite translation error for each channel and calculates the Doppler in the mobile link between the satellite transponder and the median Doppler line of each spot beam on the earth or each UT. The SBS measures the differential Doppler of the UT relative to the median Doppler line and derives its fractional Doppler, and uses the fractional Doppler to determine the position of the UT and calculate its Doppler of the traffic channels in the mobile link. The UT corrects the mobile link Doppler under the guidance of the SBS.

摘要： Mobile stations correct their frequencies using a signal received from the moving relay station including correction of any Doppler shift caused by the satellite's movement. The mobile station includes a receiver for receiving a paging channel signal broadcast by the moving relay station and demodulators and decoders for decoding the information in the paging channel signal. Using the decoded information, the mobile station can determine an estimate of its position within the communication system. The mobile station can also determine a frequency error and a Doppler shift using the decoded information and the position estimate. A frequency controlling signal is determined using the determined frequency error and the Doppler shift. A controlled reference oscillator then uses the frequency correcting signal as a control input signal. Finally, the mobile station contains a transmitter for transmitting a signal using the voltage controlled oscillator as a reference.

摘要： A satellite communications network tuning system which consumes very little communications bandwidth is disclosed. The network has a first terminal for transmitting and receiving signals, a second terminal in communication with the first for transmitting signals and a satellite for receiving signals from the terminals and retransmitting them. The frequency of the retransmitted signals is offset from the frequency at which the signals were received. A method according to the present invention for compensating the transmit frequency of the second terminal for the satellite frequency offset comprises transmitting a signal from the first terminal to the satellite at a first frequency, receiving the retransmitted signal from the satellite at the first terminal at a second frequency, the second frequency being offset from the first frequency by the satellite, measuring, at the first terminal, the difference between the first frequency and the second frequency to obtain an offset, transmitting the offset from the first terminal to the second terminal, and adjusting the transmit frequency of the second terminal using the offset.
