  • Decoding apparatus and method in a broadband wireless access communication system
    Patent number: 8379510
    Abstract: A decoding apparatus and method in a BWA communication system are provided, in which an ID-based decoder controller detects an ID from a data block by partially decoding the data block, and if the ID indicates that the data block is not for the receiver, outputs a control signal commanding non-decoding for the data block, a bitmap table controller indicates the data block as a non-decoding data block in a bitmap table according to the control signal, and a decoder distinguishes data blocks to be decoded from non-decoding data blocks based on the bitmap table, decodes the data blocks to be decoded and outputs the decoded data blocks, and simply outputs the non-decoding data blocks without decoding.

  • Apparatus and method for processing input/output data in communication system
    Publication number: 20070189233
    Abstract: An apparatus and method for processing input/output data in a communication system is disclosed. By adding a controller that adjusts timing intervals between a first buffer having a first timing interval and a second buffer having a second timing interval, buffer usage can be minimized.
