Evaluation and comparative analysis of cognitive radio network with FAHP for next generation wireless technology

Abstract

Today wireless communication networks are dominating the digital newlineconnectivity in the world. The emergent demand for future generation newlinenetworks can be met by increasing the frequency bandwidth, spectral newlineefficiency, base station capability, multiple antenna, and multicarrier newlinetechniques with flexible spectrum allocation. Furthermore, MIMO can newlinepotentially collaborate with any modulation or multiple access techniques for newlineunderutilized spectrum. A proficient key to overcome the under used newlinespectrum is cognitive radio technology, which obtain the available spectrum newlineover Reconfigurability and capability. It involves four key roles of spectrum newlinesensing, analysis, decision and adaptation. In addition, automation of newlineresponsibilities related to optimization, network planning and interference newlinemanagement is required to ensure cost-efficiency. These optimizations are newlinetailored for local data traffic. Currently the fourth generation systems (4G) and Developing Technologies fifth Generation systems (5G) are link the world from high newlinespeed of wireless connectivity, which can provide a data rate of 100-300 newlineMbps from the system. Fifth generation is nothing but New Radio (NR) smart newlinetechnology that interconnects the entire world without bounds. Fifth newlinegeneration technologies offers high speed of voice call and expected data newlinebroadcast together in advanced mobile communication. It is expected to newlinecreate an important transformation and more service benefits to the world newlinecompared to 4G. newline newline
