摘要： Methods and apparatus for communication between terminals and an access node in a multiuser multicarrier communications network are described. The access node may be a satellite access node. Terminals are configured to perform initial estimation and tracking of channel offsets and to estimate channel offsets for future packets to be transmitted by the terminal. In some embodiments the channel offsets comprise mobility related channel offsets due to the relative movement between the access node and the plurality of terminals. Transmissions from the terminals to the access node are pre-compensated for the channel offsets, so that the aggregate signal received by the access node occupies a bandwidth greater or equal to the maximum signal bandwidth of any individual terminal. Terminal transmissions may overlap in frequency and time on the ground, but arrive orthogonally at the access node.

摘要： A method in a receiver node (110, 115) is disclosed. The method comprises converting (604) a received time-domain signal (305, 405) to a frequency-domain signal, and obtaining (608), for the frequency-domain signal, an estimate of a frequency offset between a particular transmitter of one or more transmitters of interest and a receiver of the receiver node. The method comprises obtaining (612) a frequency compensated signal by applying a first frequency offset to compensate for the estimated frequency offset, and obtaining (616) a first channel estimation from the frequency compensated signal. The method comprises obtaining (620) a second channel estimation from the first channel estimation by applying a second frequency offset to the estimated channel, wherein the second frequency offset is the opposite of the first frequency offset.

摘要： A transmitter transmits payload data using Orthogonal Frequency Division Multiplexed (OFDM) symbols, the transmitter comprising a frame builder configured to receive the payload data to be transmitted and to receive signalling data for use in detecting and recovering the payload data at a receiver, and to form the payload data into data-units for transmission. A modulator is configured to modulate a plurality of sub-carriers of one or more OFDM symbols with the signalling data and the payload data in accordance with a modulation scheme to provide for each of the plurality of sub- carriers a modulation symbol, a prefixing circuit prefixes a guard interval to the one or more OFDM symbols, and a transmission circuit transmits the one or more OFDM symbols. The modulator includes a I/Q interleaver which is configured to receive a real component of the modulation symbol of each of the one or more sub-carriers of the one or more OFDM symbols and to interleave the real component of the modulation symbols differently to the imaginary component. By interleaving the real and imaginary components of the modulation symbols differently for transmission there is a greater likelihood of recovering one or both of the signalling data and the payload data.
