Abstract
Official abstract text for this publication.
A method and apparatus for transmitting and receiving a preamble having sequence information for an OFDM system is provided. The preamble transmission method includes generating a preamble block including at least one frame having a header with a known sequence and a code block containing control information and transmitting the preamble block mapped to Orthogonal Frequency Division Multiplexing (OFDM) cells by repeating in frequency axis direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A preamble generation method comprising: coding and modulating control information into one or more Forward Error Correction (FEC) blocks; adding a header in front of each of the one or more FEC blocks; repeating cyclically a part of the one or more header-inserted FEC blocks to fill a preamble block, the preamble block including the one or more header-inserted FEC blocks and the part; and mapping the repeated part of the one or more header-inserted FE…
