  • Transmission for half-duplex relay in fading channel and rateless code configuration
    Patent number: 8588112
    Abstract: In one aspect of the invention, a method for transmission in a wireless communication system includes selecting by a signal destination one of a source-destination direct transmission, a decode-forward relay transmission, and a compress-forward transmission, responsive to channel gains between a signal source and a relay, between the signal source and the signal destination, and between the relay and the signal destination; informing a selected transmission mode from the selecting step to the signal source and the relay; and operating in the selected transmission mode by the relay.

  • LT decoding and retransmission for wireless broadcast
    Patent number: 8539299
    Abstract: Methods and systems for doped rateless retransmission include receiving ratelessly coded symbols. An attempt is made to decode the coded symbols using a processor by creating an associated code graph that represents the structure of the rateless code used by the symbols. If the decoding attempt fails, an input node is selected from the code graph using a metric that gauges the number and degree of connections to the input node based on the code graph structure. The selected input node is then requested for retransmission of the selected input node by a feedback channel.
