多维高分辨率信道探测是移动的无线电波传播分析、信道建模和链路性能评估的一种方法。针对该应用，描述了天线阵列架构设计、校准和最大似然信道参数估计框架（RIMAX）。根据可用的测量维度，该算法估计多度量路径权重矩阵的四个系数，即到达方向、离开方向、到达时间延迟和镜面路径的多普勒频移。此外，密集的多径分量的分布漫散射造成的统计模型的参数估计。计算额外的可靠性措施，以提高估计的鲁棒性。
Multidimensional high resolution channel sounding is a method of wave propagation analysis, channel modeling, and link performance evaluation in mobile radio. For this application antenna array architecture design, calibration, and a maximum likelihood channel parameter estimation framework (RIMAX) is described. Depending on the available measured dimensions, the algorithm estimates the four coefficients of the polymetric path weight matrix, the direction of arrival, the direction of departure, the time delay of arrival, and the Doppler-shift of the specular paths. Moreover, the parameters of a statistical model of the dense multipath components resulting from distributed diffuse scattering are estimated. Additional reliability measures are calculated to enhance the robustness of the estimate.
