摘要
基于地面数字电视国标ADTB-T规格,采用CMA+LMS混合均衡算法配合有效的切换控制使均衡器获得良好的收敛速度和基础性能。同时,针对传统均衡器运算量过大的现象,提出了一种降低更新频率的算法,在保证基础性能的条件下有效地减小均衡器的硬件开销。
According to the National DTI'B 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.
