摘要
En 中文
This paper investigates distributed beamforming networks composed of multiple groups of transmitters where each group consists of two transmitters. The goal is to jointly optimize the phase components at the transmitters and the orientation angles of the groups that maximize the radiated energy over an angular sector containing an adversary while placing a null towards the client in order not to obfuscate the client. Since the optimization problem is non-convex, it is intractable to obtain the optimal solution in closed-form. To this end, we propose a non-iterative closed-form solution by adopting a group-wise nullforming approach where each group independently creates a null to the client. The effectiveness of the proposed scheme is validated through numerical simulations.
