  • Method and device for transferring data in a multi-carrier system having parallel concatenated encoding and modulation
    Patent number: 8179987
    Abstract: The invention relates to a transmitter-receiver pair for improved data transmission in a multi-carrier system and to a corresponding method, according to which a chain coding is used. To this end, a transmitter has a first coding stage, a transmission-demultiplexer stage, a second coding stage, a modulator stage, a transmission multiplexer stage and a multi-carrier modulator, whereby said transmission-demultiplexer stage and the transmission multiplexer stage are controlled by a bit loading device. Similarly, the receiver has a multi-carrier demodulator, a receiver demultiplexer stage, a first decoding stage, a receiver multiplexer stage and a second decoding stage, whereby the receiver multiplexer stage and demultiplexer stage are in turn controlled by the bit loading device.

  • Method for reducing signaling overhead in a multicarrier system with dynamic bit allocation and corresponding transmitter/receiver device
    Patent number: 7460465
    Abstract: A method for reducing signaling overhead in a multicarrier system with dynamic bit allocation per subcarrier and a corresponding transmitter/receiver device, are provided wherein an established bit allocation table (BAT) that is provided with an index (I) is stored in a BAT storage device (LUT). In order to reduce signaling overhead, only the corresponding index (I) of an existing bit allocation table is transmitted (S6).
