论文摘要
本文研究了具有集成感应和通信（ISAC）的系统中光束形成设计的优化，在该系统中，基站（BS）发送信号，以同时进行多源通信和雷达传感。我们旨在最大程度地提高多源通信的能源效率（EE），同时保证单个雷达梁图案增长的传感需求。这个问题是一个复杂的非概念分数程序，这是一个具有挑战性的问题。通过适当地重新加定问题，然后应用连续的凸近似技术（SCA）和半芬矿放松（SDR），我们提出了一种迭代算法来解决此问题。从理论上讲，我们证明了SDR引入的放松非常紧密。数值结果验证了所提出的算法的有效性。
This paper investigates the optimization of beamforming design in a system with integrated sensing and communication (ISAC), where the base station (BS) sends signals for simultaneous multiuser communication and radar sensing. We aim at maximizing the energy efficiency (EE) of the multiuser communication while guaranteeing the sensing requirement in terms of individual radar beampattern gains. The problem is a complicated nonconvex fractional program which is challenging to be solved. By appropriately reformulating the problem and then applying the techniques of successive convex approximation (SCA) and semidefinite relaxation (SDR), we propose an iterative algorithm to address this problem. In theory, we prove that the introduced relaxation of the SDR is rigorously tight. Numerical results validate the effectiveness of the proposed algorithm.
