Training sequence for symbol boundary detection in a multicarrier data transmission system
First Claim
1. A training protocol for use in estimating symbol boundary timing at a receiver of a multicarrier data transmission system, wherein said training protocol transmits a series of training symbols over a wire to the receiver, wherein at least two of the training symbols in the series of training symbols being identical symbols that are preceded or succeeded by different training symbols.

Abstract
An improved training sequence for acquiring symbol boundary timing at a receiver of a data transmission system is disclosed. One aspect pertains to an improved training sequence wherein groups of identical symbols are transmitted by a transmitter. These symbols can be supplied to the transmitter in a time domain or a frequency domain manner. The improved training sequence facilitates symbol boundary determination at a receiver.
