在太赫兹频率下工作的超宽带通信系统将需要对传播信道的透彻了解。因此，50 GHz宽的室内无线电信道的广泛的测量活动，提出了275和325 GHz之间的频率。根据到达角和离开角在空间上分辨各个射线路径。MIMO信道以2×2配置记录。采用一种先进的频域射线跟踪方法对太赫兹波室内传播信道进行了确定性仿真。射线追踪结果与测量数据进行了验证。此外，测量值用于射线跟踪算法的校准。由此产生的光线跟踪精度进行了讨论。
Ultra broadband communication systems operated at THz frequencies will require the thorough knowledge of the propagation channel. Therefore, an extensive measurement campaign of 50 GHz wide indoor radio channels is presented for the frequencies between 275 and 325 GHz. Individual ray paths are resolved spatially according to angle of arrival and departure. A MIMO channel is recorded in a 2×2 configuration. An advanced frequency domain ray tracing approach is used to deterministically simulate the THz indoor propagation channel. The ray tracing results are validated with the measurement data. Moreover, the measurements are utilized for the calibration of the ray tracing algorithm. Resulting ray tracing accuracies are discussed.
