论文摘要
在这封信中，我们调查了集成传感和通信（ISAC）系统的联合接收器设计，在该系统中，通信信号和目标回声信号同时接收并处理，以实现两个功能之间的平衡性能。特别是，我们提出了两种设计方案，以解决接收信号处理的关节感应和通信问题。 {\ color {black}第一个基于最大似然（ML）检测，最小平方误差（MMSE）估计和干扰取消（IC），而另一个则为构成非IC设计的检测器独立于目标估计值定制的MMSE估计器。我们表明，通过考虑到通信信号的结构信息，非IC方法的表现优于IC方法，并实现了最佳性能。}数值结果可以验证所提出的最佳设计的有效性。
In this letter, we investigate the joint receiver design for integrated sensing and communication (ISAC) systems, where the communication signal and the target echo signal are simultaneously received and processed to achieve a balanced performance between both functionalities. In particular, we proposed two design schemes to solve the joint sensing and communication problem of receive signal processing. {\color{black} The first is based on maximum likelihood (ML) detection, minimum mean squared error (MMSE) estimation and interference cancellation (IC), and the other formulates a tailored MMSE estimator for target estimation that is independent to the detector, which form a Non-IC design. We show that with the structural information of the communication signal taken into account, the Non-IC approach outperforms the IC method and achieves optimal performance.} Numerical results are provided to validate the effectiveness of the proposed optimal designs.
