Abstract: A satellite receiver comprises a front-end, demodulator and an LDPC decoder. The front-end receives a DVB-S2 LDPC coded signal and provides a down-converted signal to the demodulator. The latter demodulates the down-converted signal and provides a demodulated signal to the LDPC decoder. The LDPC decoder has a partially parallel architecture and partitions the bit node messages into N/360 groups and the check node messages into q groups, where q=M/360. Each group is processed by 360 bit node processors or 360 check node processors, respectively. Illustratively, the LDPC decoder includes a memory that is partitioned such that messages associated with bit node groups are consecutively addressed. Alternatively, the LDPC decoder includes a memory that is partitioned such that messages associated with check node groups are consecutively addressed.

Abstract: A receiver comprises a number of fingers, each finger providing symbols associated with a path of a received multipath signal, and a maximal ratio combiner (MRC) that activates to combine the symbols when the symbols are available. In an illustrative embodiment a receiver is a CDMA receiver and comprises a number of fingers, an interface, and an MRC. Each finger provides symbols asociated with a path of a received multipath signal for the various channels conveyed therein, the interface provides an indiction when symbols from the fingers are ready for processing to the MRC, which then activates to combine those symbols from the fingers that are asociated with the same channel. Illustratively, the interface includes a priority encoder for selecting different channels for processing by the MRC. Further, the MRC can be configured to operate with a clock rate that is greater than a chip rate.

Abstract: 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.
