HDTV中分层结构的均衡器的设计

Design of a hierarchical equalizer in HDTV

针对 Ｈ Ｄ Ｔ Ｖ 中均衡器硬件规模过于庞大的问题，提出了删除抽头的和分层结构的均衡器设计。这两种思想都可以大幅度压缩均衡器的硬件规模，分层结构还可以解决准自适应均衡器收敛速度较慢的问题；

The equalizer in HDTV occupies too much hardware resources. To solve the problem, this paper proposes tap\|decimated equalizer and hierarchical equalizer. Both of which can greatly reduce the hardware resources used in HDTV. The latter can solve the problem of slowness of convergence are also applicable to any channel that has identifiable long delayed ghost interference.
