Based on the analysis of outdoor measured data in Manhattan[3,4] published by New York University, this paper summarizes the statistical characteristics of the data, and proposes a spatial lobe joint time cluster modeling method, which can be applied to establish the frequency coverage of 500 MHz-100 GHz, the transmission bandwidth can reach 800 MHz, and supports a 3-D MIMO channel impulse re-sponse model for multiple antenna arrays. The model adds the influence of environmental factors such as air humidity, air pressure, vegetation and so on, and then elaborates the steps of concrete model building and parameter generation. Finally, the corresponding path loss, power delay spectrum, angular power spectrum and RMS delay spreads and the angular spreads are obtained according to the simulation conditions. In order to ensu
