摘要
提出了一种多天线-正交频分复用(MIMO-OFDM)的DVB-T(地面数字视频广播)系统实现方案。通过将MIMO技术与OFDM技术结合,能够充分发挥各自特点,从而更有效地获得分集增益,提高系统容量及性能。理论分析及计算机仿真证明,与传统的单天线系统相比,该方案具有明显的性能优势。
A scheme of multiple-antenna OFDM(MIMO-OFDM)for DVB-T is presented in this paper.Combined MIMO with OFDM,diversity gains can be obtained to improve the performance of the systems effectively.Theoretical analysis and simulation show that our scheme outperforms vastly the traditional DVB-T systems.[
