Method and apparatus for frame alignment in discrete multitone transceivers

摘要

A method and apparatus for determining frame alignment in a discrete multitone transceiver by determining a rotation of the coefficients of the shortening channel impulse response for which inter symbol interference (ISI) is minimal. The ISI is determined by multiplying the average value of a transmitted discrete multitone symbol and multiplying it by the coefficients of the shortening channel impulse response in a given rotation.
