摘要:
垂直分层空时码技术是多输入多输出-正交频分复用系统常采用的一种检测方法，但是其计算方法非常复杂.空频分组码是一种比较有效的技术，可以提高数据在多道无线信道传输的效率.本文提出一种将空频分组码与垂直分层空时码系统相结合的方法，并通过使用turbo码的迭代检测来改善信道估计性能.实验证明：该方法不仅可以简化系统的复杂度，还使得系统在快衰落信道中也具有较好的性能.
Abstract:
 Vertical bell laboratories layered space\|time coding(V\|BLAST) is an effective detection method for multiple\|input multiple\|output orthogonal frequency division multiplexing(MIMO\|OFDM) systems, but has a large computational complexity. Space frequency block code(SFBC) is a new bandwidth efficient technique and can achieve high data rates over the wideband wireless channel. Therefore, we proposed combing SFBC technology with V\|BLAST systems, and used the turbo iterative detection algorithm to improve the channel estimation performance. The simulation results show that the scheme not only reduces the complexity of the systems, but also increases the system performance in fast fading channel.
