  • Apparatus and method for coding packet
    Patent number: 10122503
    Abstract: An apparatus for coding a plurality of packets in a multi-antenna system, the apparatus including a processor configured to determine space-time codes of the plurality of packets sequentially from a subsequent packet to maximize an average throughput of the plurality of packets, and a transmitter configured to transmit the plurality of packets to an antenna, is provided.
    Type: Grant

  • Transmission, reception and system using multiple antennas
    Patent number: 9590716
    Abstract: The present disclosure in some embodiments provides transmission, reception and an apparatus using multiple antennas. A transmission apparatus in an embodiment may include first to M-th transmission antennas, where M is a natural number?2; first to L-th encoders, where L is a natural number?2; and first to M-th transmission signal generators. The l-th encoder (where l=arbitrary natural number between 1 and L) receives an l-th symbol sequence and generates first to M-th encoded symbol sequences by encoding the received l-th symbol sequence according to an l-th multiple antenna transmission scheme. The m-th transmission signal generator (where m=arbitrary natural number between 1 and M) combines m-th encoded symbol sequences generated by the encoders to generate a signal to be transmitted via the m-th transmission antenna.

  • TRANSMISSION, RECEPTION AND SYSTEM USING MULTIPLE ANTENNAS
    Publication number: 20140321557
    Abstract: The present disclosure in some embodiments provides transmission, reception and an apparatus using multiple antennas. A transmission apparatus in an embodiment may include first to M-th transmission antennas, where M is a natural number?2; first to L-th encoders, where L is a natural number?2; and first to M-th transmission signal generators. The I-th encoder (where I=arbitrary natural number between 1 and L) receives an I-th symbol sequence and generates first to M-th encoded symbol sequences by encoding the received I-th symbol sequence according to an I-th multiple antenna transmission scheme. The m-th transmission signal generator (where m=arbitrary natural number between 1 and M) combines m-th encoded symbol sequences generated by the encoders to generate a signal to be transmitted via the m-th transmission antenna.
