In this paper, a two-hop nonregenerative multiple-input multiple-output relay system is
investigated, where the relay node relies on harvesting the radio frequency energy …

Zero-forcing beamforming under per-antenna power constraint (PAPC) is considered in this
paper, and the objective is to maximize the minimum user information rate. A parallel low …

In this article, a dual-hop amplify-and-forward (AF) multiple-input multiple-output (MIMO)
relay communication system is studied. With a splitting (PS) protocol, the relay node …

With the rapid increase of data amount in many fields, such as machine learning and
networked systems, optimization-based methods inevitably confront the computational …

Zero-forcing beamforming (ZFBF) under perantenna power constraint (PAPC) is a popular
research topic. A survey is carried out in this paper to show the important results in the …

This paper proposes a design of multi-user beamformer under a per-antenna power
constraint (PAPC). The proposed beamforming method effectively utilizes the antenna …

In Multiple-input multiple-output (MIMO) broadcast channels (BCs), the transmitter
simultaneously broadcasts signals to multiple receivers at same frequency band, resulting in …

This letter proposes a new algorithm for solving the optimal zero-forcing beamforming
problem that maximizes the user achievable rate with restriction on the per-antenna element …

In this paper, we investigate a zero-forcing beamformer design with signed power-of-two
coefficients for rural applications. In this design, the minimum user information rate is taken …

This paper proposes a beamforming method under a per-antenna power constraint (PAPC).
Although many beamformer designs with the PAPC need to solve complex optimization …
