Abstract: Receivers and methods of operation are described. A receiver for a modulated signal of a communication system, comprises a demodulator to demodulate the received modulated symbols of a received signal into received soft-bits. A hard-decision decoder is arranged and configured to decode the received soft-bits into decoded bits. A feedback loop is arranged to provide feedback from the hard decision decoder to the demodulator. the feedback loop is configured to re-encode the decoded bits from the hard-decision decoder into re-encoded bits. The demodulator is further arranged and configured to iteratively demodulate the received modulated signal using an output of the feedback loop.

Abstract: A system includes a transmitter configured to emit a signal. The system includes a control system, configured to determine a geographical mitigation region of a satellite, determine the transmitter is located within the geographical mitigation region, and modify an operation of the transmitter to mitigate interference with an observation sensing activity of the satellite.

Abstract: A first-transceiver for use in an antenna diversity scheme. The first-transceiver comprises a first-time/clock-generation-unit; a first-receiver; and a first-transmitter. The first-receiver is configured to receive a wireless second-alignment-signal from a second-transceiver with a second-time/clock-generation-unit. The wireless second-alignment-signal is representative of a state of the second-time/clock-generation-unit. The first-transceiver is configured to set the first-time/clock-generation-unit, based on the wireless second-alignment-signal, to reduce an alignment-error between the first-time/clock-generation-unit and the second-time/clock-generation-unit. The first-transmitter is configured to transmit a wireless first-transmission-signal, in accordance with the first-time/clock-generation-unit, as part of the antenna diversity scheme. The first-transmission-signal corresponds to a second-transmission-signal that is transmitted by the second-transceiver. The antenna diversity scheme comprises aligned transmission of both the first-transmission-signal and the second-transmission-signal.
