摘要

通过考虑到传输信号的几个维度，如空间、频率、周期和时间，MIMO-OFDM系统与矩阵解决方案相比，可以提高频谱效率和改进可识别性。在本文中，我们评估MIMO-OFDM系统的几何场景，其中窄带近似违反。为此，提出了一种新的数据模型，以更好地表示系统在宽带信号存在下的行为。此外，我们还放宽了发射天线的数量等于发射符号的数量的假设。

Evaluation of Space-Time-Frequency (STF)-Coded MIMO-OFDM Systems in Realistic Channel Models

By taking into account several dimension of the transmitted signal, such as space, frequency, period and time, MIMO-OFDM systems allow an increased spectral efficiency and an improved identifiability in comparison to matrix solutions. In this paper, we evaluate MIMO-OFDM systems for geometric scenarios where the narrow band approximation is violated. To this end a new data model is proposed to better represent the behavior of the system in the presence of wide band signals. Moreover, we also relax the assumption that the amount of transmitted antennas is equal to the number of transmitted symbols.
