In general, software as a service (SAAS) is a model for the distribution of software that
customers have access to on the Internet. In SAAS, a service provider hosts the application …

In this paper, we propose a new multiple-input multiple-output (MIMO) communication
system with movable antennas (MAs) to exploit the antenna position optimization for …

Conventional beamforming with fixed-position antenna (FPA) arrays has a fundamental
trade-off between maximizing the signal power (array gain) over a desired direction and …

This paper describes the synthesis method of linear array geometry with minimum sidelobe
level and null control using the particle swarm optimization (PSO) algorithm. The PSO …

Multiple-input multiple-output (MIMO) system has been the defining mobile communications
technology in recent generations. With the ever-increasing demands looming towards the …

With research efforts gearing up to build the sixth-generation (6G) mobile communications, it
is only logical to seek new mobile technologies that can provide the next generational leap …

This paper investigates a multiuser millimeter-wave (mmWave) uplink system in which each
user is equipped with a multi-antenna fluid antenna system (FAS) while the base station …

Linear and circular arrays are optimized using the particle swarm optimization (PSO)
method. Also, arrays of isotropic and cylindrical dipole elements are considered. The …

Unit-modulus least squares (ULS) problems arise in many applications, including phase-
only beamforming, sensor network localization, synchronization, phase retrieval, and radar …

A novel multiuser communication system with movable antennas (MAs) is proposed, where
the antenna position optimization is exploited to enhance the downlink sum-rate. The joint …
