Finally, the channel capacity at THz frequency band is evaluated by the reconstructed CIRs generated by the GBSM using the measured statistical values and the 3GPP default values.

In addition, a new intra-cluster power allocation model based on measurements is proposed to characterize the effects of sparsity in the delay domain of the 3GPP channel model.

Furthermore, based on this dataset, we propose an end-to-end model that jointly optimizes the video understanding objective with knowledge graph embedding, which can not only better inject factual knowledge into video understanding but also generate effective multi-modal entity embedding for KG.
