Abstract :
A new joint algorithm between timing and fractionally-spaced equalization is proposed. It adopts Gardner algorithm instead of simple down-sampling in conventional fractionally-spaced equalization, which overcomes the problem that the filter can´t compensate timing error. And CMA-MMA Equalization is used to solve the problem that timing can´t converge under the condition of severe channel aberration.
