| Abstract: | According to the National DTTB Standard ADTB-T, the CMA+LMS omnibus algorithm and effective switching control are used to achieve the high convergent speed and well basic performance. At the same time, a reduced-complexity algorithm is also presented in allusion to the enormous calculation of conventional equalizer. The algorithm can effectively reduce the hardwire cost of the equalizer without the loss of basic performance. |
