通过2.35 GHz室内场景下的现场信道测量，验证了IMTAdvanced(International Mobile Telecications-Advanced)信道模型中的天线建模方法。首先，以实际天线为参考，记录了2x2 MIMO信道冲激响应(CIR)。其次，根据现有的IMT-Advanced信道模型，利用实际天线的场方向图和从相似场景测量中提取的更新的空间参数来重建CIR。然后，从相干带宽、特征值离散度、中断容量和遍历信道容量等方面对现场CIRS和重构CIRS进行了比较。结果表明，重构结果在相干带宽上接近真实结果，并正确地描述了频域内的统计特性。与现场CIRS相比，两种天线的重构CIRS具有更大的空间相关性，导致对5%的信道中断容量估计偏低。由于忽略了天线之间的耦合和天线的近场效应，这种建模方法会对无线信道的特性，特别是对空间特性产生很大的影响。
In this paper, the antenna modeling method in the International Mobile Telecommunications-Advanced (IMTAdvanced) channel model is validated by field channel measurements in the indoor scenario at 2.35 GHz. First, the 2x2 MIMO channel impulse responses (CIRs) are recorded with practical antennas as references. Second, the CIRs are reconstructed from the available IMT-Advanced channel model with field patterns of the practical antennas and updated spatial parameters extracted from the similar scenario measurements. Then comparisons between the field CIRs and the reconstructed CIRs are made from coherent bandwidth, eigenvalue dispersion, outage capacity, and ergodic channel capacity. It is found that the reconstructed results closely approximate real results in the coherent bandwidth and correctly describe the statistical characteristics in frequency domain. Compared to the field CIRs, the spatial correlation of the reconstructed CIRs with either type of antenna have a wider range, that causes the underestimation of the 5% channel outage capacity. Due to the negligence of the coupling among the antennas and the near field effect of antenna, this modeling method will have a great impact on the characteristic of radio channel, especially on the spatial characteristics.
