Abstract
An integrated circuit arranged and constructed to determine an upper data rate for a variable data rate signal and method thereof includes a buffer, comparator, and combiner that are operable to compare a characteristic, such as an energy statistic of a number of partial symbols constructed from the variable data rate signal to a first threshold that corresponds to the number to provide a first comparison; process the variable data rate signal at a first data rate when the first comparison is favorable; compare the characteristic to a second threshold that corresponds to the number to provide a second comparison; and combine the partial symbols to provide other partial symbols at a second data rate that is less than the first data rate when the second comparison is favorable.
