摘要： A satellite communications system comprises a transmitting ground station, including a transmitter and a receiver, a satellite transponder and a receiving ground station. The transmitter transmits an uplink signal to the satellite transponder, which broadcasts the received uplink signal as a downlink signal to the receiving ground station. The transmitting ground station monitors the downlink signal through the receiver and calculates log-likelihood ratios (LLRs) as a function of the monitored downlink signal. These LLRs are illustratively stored in a look-up table, which are then transmitted to the receiving ground station for use in recovering data from a received data signal.

摘要： An apparatus includes a first signal receiving module, a second signal receiving module, and a signal transmitting module. The first signal receiving module is coupled between a first signal point and a third signal point for receiving a first RF signal from the first signal point. The first signal receiving module down-converts the first RF signal for providing a first down-converted signal at the third signal point. The second signal receiving module is coupled between a second signal point and the third signal point for receiving a second RF signal. The second signal receiving module down-converts said second RF signal for providing a second down-converted signal at the third signal point. The signal transmitting module is coupled between the first and second signal points and the third signal point for receiving a third RF signal from the third signal point. The signal transmitting module up-converts the third RF signal for selectively providing an up-converted signal at one of the first and second signal points in response to a selection signal.

摘要： A method for hierarchically block coding a packet stream includes the steps of appending a packet error correction code to each packet in the packet stream and appending a block error correction code to successive blocks of packets in the packet stream to form a hierarchically error correction coded packet stream. This packet stream is then transmitted through a communications channel. Errors are corrected in each block of packets in response to each block error correction code and errors are corrected in each packet in each block in response to each packet error correction code.
