  • Space frequency block code signal processing and relaying system
    Patent number: 8897208
    Abstract: A space frequency block code signal relaying system is provided. The space frequency block code signal relaying system includes a signal detecting unit which receives, via a radio channel, a source signal sent from a source station and detects the received signal; a relay signal generation unit which generates a relay signal corresponding with the source signal transmitted from the source station to a destination node based on the received signal, the source signal and the relay signal being signals encoded in a Space Frequency Block Code (SFBC) scheme; and a signal transmitting unit which transmits the relay signal to the destination node.
    Type: Grant

  • Relay-based communication system and method processing signal without cyclic prefix
    Patent number: 8451916
    Abstract: A relay-based communication system and method processing a signal without a cyclic prefix is provided. An apparatus for generating a relay signal includes a signal receiving unit which receives a source signal transmitted from a source node to a relay node and detects a received signal, a signal conversion unit which extracts samples corresponding to a first time duration from the received signal, sums the received signal and the extracted samples in a second time duration, and generates a converted received signal, a relay signal generation unit which generates a relay signal cooperating with the source signal based on the converted received signal according to a space frequency block code (SFBC) scheme, and a signal transmission unit which transmits the generated relay signal to a destination node.
