  • STFBC coding/decoding apparatus and method in an OFDM mobile communication system
    Patent number: 7693041
    Abstract: A mobile communication system for modulating input data with a specific size into an OFDM (Orthogonal Frequency Division Multiplexing) symbol and transmitting the OFDM symbol through at least two different antennas. A replica generator generates replica data by cyclically-circulating the input data. An encoder generates a first antenna signal and a second antenna signal by encoding the input data and the replica data. A first IFFT (Inverse Fast Fourier Transform) block generates a first OFDM symbol by performing IFFT on the first antenna signal, and a second IFFT block generates a second OFDM symbol by performing IFFT on the second antenna signal. A first antenna transmits the first OFDM symbol, and a second antenna transmits the second OFDM symbol.

  • STFBC coding/decoding apparatus and method in an OFDM mobile communication system
    Patent number: 7483366
    Abstract: A mobile communication system modulates input data with a specific size into an OFDM symbol and transmits the OFDM symbol through an antenna. In the mobile communication system, a replica generator generates OFDM symbol data by cyclic-circulating the input data by a predetermined cyclic circulation distance d, and outputs a stream of the input data and the replica data as a data stream.

  • OAM packet data transmission method and ethernet passive optical network including control multiplexer for the same
    Publication number: 20040085905
    Abstract: A method for transmitting OAM (Operation, Administration and Maintenance) packet data by a control multiplexer of an OAM sublayer in an Ethernet passive optical network (EPON) accords priority to OAM packet data over MAC (Medium Access Control) client data awaiting transmission. The control multiplexer multiplexes the OAM packet data and the MAC client data according to the priority and transmits the multiplexed data to the MAC entity.

  • ARQ apparatus and method using frequency diversity in an OFDM mobile communication system
    Publication number: 20030189892
    Abstract: A transmission method and apparatus in a mobile communication system, which modulates input data with a specific size into an OFDM symbol before transmission. In the transmission apparatus, a controller determines to transmit replica data instead of the input data, if the input data is retransmission data. A replica generator generates replica data by cyclically-circulating the input data under the control of the controller. An IFFT block generates an OFDM symbol by IFFT-transforming the replica data.
