摘要

2014年8月,ATSC调整了3DTV标准,该标准是采用主移动混合传输(SC-MMH)的业务兼容3DTV, 3DTV标准采用ATSC M/H传输系统。由于M/H系统同时传输主训练序列和移动训练序列进行均衡,因此同时使用这两种训练序列可以提高ATSC 3DTV接收性能。本文介绍了LMS-DFE,并提出了一种与信道估计相结合的均衡器。并在K = 0 dB的瑞利信道和瑞利信道上进行了计算机仿真,以评价两种均衡器的性能。仿真结果表明,在半VSB帧的时间内,该均衡器在两个信道上都能很好地工作。

An equalization technique concatenated with channel estimation for ATSC 3DTV receivers
In August 2014, ATSC adapted 3DTV standard which is service compatible 3DTV using main and mobile hybrid delivery (SC-MMH), and the 3DTV standard uses the ATSC M/H transmission system. Because the M/H system transmits both main and mobile training sequences for equalization, ATSC 3DTV reception performance can be improved by using both training sequences. This paper introduces the LMS-DFE and proposes an equalizer concatenated with channel estimation. And the computer simulations were performed on Rician channel of K = 0 dB and Rayleigh channel in order to evaluate the performance of both equalizers. Simulation result shows that the proposed equalizer works well on both channels within the time of a half VSB frame.
