A method and apparatus for generating a preamble for use in DVB-C2 cable transmission standard is provided. The preamble has multiple functions including frame timing, synchronization, frequency offset estimation, system information signaling and initial channel estimation. In accordance with an implementation, a complementary sequence is inserted as a header and the complementary sequence and system signaling bits are mapped into modulation symbols for transmission on allocated even channels only of the cable transmission system.
