摘要 提出了一种M IM O(m u ltip le inpu tm u ltip le ou tpu t)-OFDM(orthogona l frequency d iv is ion m u ltip lex-ing)系统前导结构以及基于相关的帧/符号同步、载波频率同步方案,详细介绍了同步算法,并给出高斯白噪声信道和频率选择性衰落信道中的仿真结果.结果表明,这种同步方案算法复杂度低,具有较高的精度和较大的实用价值. This paper puts forward a preamble structure for MIMO-OFDM system, proposes a frame/symbol and carrier frequency synchronization scheme based on correlation, gives computer simulation of the synchronization algorithms over AWGN channel and frequency selective fading channel. Simulation results demonstrate that the synchronization scheme has low complexity and good performance.
