Abstract
Disclosed are a method for configuring a preamble for a communication system in order to effectively use a packet transmission bandwidth, a preambler, and an apparatus for generating a packet using the same. The preambler includes: a mode determining unit receiving frame characteristics information, extracting frame information to be transmitted through a preamble, and determining a transmission mode corresponding with the extracted information; and a code generation unit receiving the transmission mode information which has been determined by the mode determining unit and generating a preamble made up of a combination of sub-preamble code strings corresponding with the transmission mode.
Claims20
A preambler comprising:
- a mode determining unit configured to receive frame characteristics information, extract frame information to be transmitted through a preamble, and determine a transmission mode corresponding to the extracted frame information;
- and
- a code generation unit configured to receive information of the transmission mode which has been determined by the mode determining unit and generate the preamble that includes a plurality of sub-preambles to which sub-preamble code strings are assigned,
- wherein the transmission mode is expressed by a combination of the sub-preamble code strings assigned to the sub-preambles.
An apparatus for generating a packet, the apparatus comprising:
- a preambler including a mode determining unit that is configured to receive frame characteristics information, extract frame information to be transmitted through a preamble, and determine a transmission mode corresponding to the extracted frame information, and a code generation unit that is configured to receive information of the transmission mode which has been determined by the mode determining unit and generate the preamble including a plurality of sub-preambles to which sub-preamble code strings are assigned, a combination of the sub-preamble code strings corresponding to the transmission mode;
- a header generation module configured to receive the frame characteristics information and generate a header by using information other than the frame information transmitted through the preamble;
- and
- a payload generation module configured to receive data and generate a payload having a length obtained by subtracting the combination of the sub-preamble code strings and a length of the header from a packet length.
A method for configuring a preamble, the method comprising:
- extracting frame information to be transmitted through a preamble from frame characteristics information and determining a transmission mode corresponding to the extracted frame information;
- and
- generating sub-preamble code strings corresponding to the determined transmission mode, and generating the preamble including a plurality of sub-preambles to which the sub-preamble code strings are assigned,
- wherein the transmission mode is expressed by a combination of the sub-preamble code strings assigned to the sub-preambles.
