Digital antenna array (DAA) is a smart antenna with multi channels digital beamforming, usually by using fast Fourier transform (FFT). The development and practical realization of digital antenna arrays theory started in 1962 under the guidance of Vladimir Varyukhin ( USSR ).
BCOM systems focus on delivering the value of business communications across multiple vendors and are user-centric. [ 12 ] [ 13 ] [ 14 ] Through optimized workflow processes, user-centric profiles, and business process integration, BCOM enables an organization to maximize the value of its investment and reduce operational costs.

Business support systems (BSS) are the components that a telecommunications service provider (or telco) uses to run its business operations towards customers. Together with operations support systems (OSS), they are used to support various end-to-end telecommunication services (e.g., telephone services). [ 1 ]
In computational complexity theory, a complexity class is a set of computational problems "of related resource-based complexity". [1] The two most commonly analyzed resources are time and memory. In general, a complexity class is defined in terms of a type of computational problem, a model of computation, and a bounded resource like time or memory.
A data acquisition system is a collection of software and hardware that allows one to measure or control the physical characteristics of something in the real world. A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software.
Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires , optical fibers , wireless communication using radio spectrum , storage media and computer buses .
