Abstract

This paper proposes a new design of low complexity fractionally spaced equalizer to eliminate strong ISI in wireless broadcasting channel of DTTB system. In the design, a CMA+LMS integrated algorithm with effective switching control is adopted, which can gain high convergent speed and well basic performance. Furthermore, a reduced-frequency algorithm is also adopted to deal with the enormous calculation of conventional equalizer, and profit from which the hardware cost of the new design has been reduced evidently.
