Abstract (en)
[origin: WO2008001293A2] A communication device configured for the use of transporting a communication signal having a specialized preamble allowing for increased bandwidth efficiency is disclosed. The communication device includes a first device configured to manipulate a block transmission scheme, such as OFDM or SCBT signal, having a block size equal to N, wherein N is an integer greater than 1, wherein the block transmission signal has a preamble with a symbol configuration such that a percentage of all symbols of the preamble can each be used for all of frequency offset estimation, clock synchronization and channel estimation.
