INTERFERING IN TIME-DIVISION DUPLEX COMMUNICATION
A computer readable storage medium is presented, having computer readable program instructions thereon for causing a processor to carry out the steps of: sub-dividing a time slot into consecutive time intervals, the time slot belongs to multiple time slots allocated to a first node for transmitting to a second node using a wireless time-division duplex communication link between the first node and the second node, the second node transmitting during separate time slots allocated to said second node; and disrupting communication between said first node and said second node by transmitting, using a transmitter, respective interference signals during at least some of said time intervals, each of said interference signals being transmitted on one of said frequency bands, wherein for at least two of said time intervals said interference signals are transmitted on different frequency band.
Transmission apparatus, transmission time fluctuation compensation method, and non-transitory computer readable medium storing transmission time fluctuation compensation program
A transmission apparatus (10) according to the present disclosure incudes: a correction value calculation unit (130) configured to calculate a correction value for correcting an initial standby time of a direct wave signal or an indirect wave signal based on a reception time of the direct wave signal and a reception time of the indirect wave signal that follows the direct wave signal, and a transmission time fluctuation compensation unit (140) configured to calculate the standby time by correcting the initial standby time using the correction value and cause the direct wave signal or the indirect wave signal to stand by in accordance with the standby time. The correction value calculation unit (130) calculates a correction value for increasing the standby time of the direct wave signal or reducing the standby time of the indirect wave signal.
Methods and devices for operating in beam hopping configuration and under a range of signal to noise ratio conditions
Methods and transceivers transmit communication frames that comprise a sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols. The sequence of N symbols encodes information according to signal-to-noise ratio associated with the communication frame.
Method and apparatus for handling communications between spacecraft operating in an orbital environment and terrestrial telecommunications devices that use terrestrial base station communications
A multiple-access transceiver handles communications with mobile stations in environments that exceed mobile station design assumptions without necessarily requiring modifications to the mobile stations. One such environment is in Earth orbit. The multiple-access transceiver is adapted to close communications with mobile stations while exceeding mobile station design assumptions, such as greater distance, greater relative motion and/or other conditions commonly found where functionality of a terrestrial transceiver is to be performed by an orbital transceiver. The orbital transceiver might include a data parser that parses a frame data structure, a signal timing module that adjusts timing based on orbit to terrestrial propagation delays, frequency shifters and a programmable radio capable of communicating from the Earth orbit that uses a multiple-access protocol such that the communication is compatible with, or appears to the terrestrial mobile station to be, communication between a terrestrial cellular base station and the terrestrial mobile station.
