Abstract
A method implemented in a multicarrier transmission system, the method comprising generating a plurality of constellation points by using one or more constellation mappers to map a plurality of special data sequences for an idle data transmission unit (IDTU), wherein the plurality of special data sequences are computed prior to the mapping such that the plurality of constellation points are essentially inner constellation points, wherein each of the inner constellation points resides in a constellation diagram that corresponds to one of a plurality of subcarriers used by the IDTU, and wherein the constellation diagram comprises a number of inner constellation points and a number of outer constellation points, with the inner constellation points being closer from an origin of the constellation diagram than the outer constellation points, and transmitting the plurality of constellation points.
