摘要

针对第二代地面数字视频广播(DVB-T2)标准，提出了一种增强的导频辅助信道估计算法。讨论了两种信道估计技术，第一种是基于三点平均技术，第二种是基于信道响应频域方向图的研究。与DVB-T2实施指南推荐的传统估计技术相比，第二种技术导致保证特定误码率(BER)要求所需的信噪比降低0.5 dB。

Modified MIMO-OFDM Channel Estimation Technique for DVB-T2 Systems

This paper proposes an enhanced pilot-aided channel estimation algorithm for the second generation of the digital video broadcast for terrestrial (DVB-T2) standard. Two channel estimation techniques are discussed, the first is based on the 3-points averaging technique, while the second is based on studying the frequency domain pattern of the channel response. The second technique leads to a 0.5 dB reduction in the SNR needed to guarantee a specific bit error rate (BER) requirement when compared to the conventional estimation technique recommended by the DVB-T2 implementation guide lines.
