The three-dimensional (3D) location optimization for reconfigurable intelligent surface (RIS) aided millimeter wave network is investigated. We first formulate the signal-tonoise ratio (SNR) maximization model by jointly optimizing the precoding vector, the RIS location and its parameter matrix in a…
Vision-based collision prediction for autonomous driving is a challenging task due to the dynamic movement of vehicles and diverse types of obstacles. Most existing methods rely on object detection algorithms, which only predict predefined collision targets, such as vehicles and pedestrians, and can…
We consider the global energy efficiency (GEE) maximization problem for the general non-regenerative MIMO relay network, under the maximum power constraints for each user and each relay. The problem is reformulated through the fractional optimization technique, and the mean square error receiver fil…
We consider the general MIMO relay network with K user pairs and R relays. The model to maximize the total signal to total interference plus noise ratio, with individual relay transmit power constraints, is set up. We constrain the precoding matrices to have orthogonal columns to guarantee multiple…
