摘要

提出了一种用于地面数字多媒体广播(T-DMB)的数字信道内中继器(DOCR)，可以有效地缓解时变选频信道中的干扰。分析了传统DOCR存在的问题，提出了一种新的能量均衡器和信道估计技术。仿真结果证实了T-DMB在时变典型城市信道中BER性能的提高。

A novel energy equalization digital on-channel repeater for T-DMB system in time-varying channels

A novel digital on-channel repeater (DOCR) for terrestrial-digital multimedia broadcasting (T-DMB) is presented to effectively mitigate the interference in time-varying frequency selective channels. Problem of conventional DOCR are analyzed, and a new energy equalizer and channel estimation techniques are proposed. Simulation results confirm the BER performance improvement of T-DMB in time-varying typical urban channel.
