Hardware problems are the most detrimental issues to channel estimates in wireless communication systems. Because of enormous number antennas at base station (BS) cellular massive multiple-input multiple-output (MIMO) systems and because one radio frequency (RF) chain per antenna is required, hardware impairments such will be quite severe. Many research publications have used a quality-cost tra...

This paper analytically reviews the performance of massive multiple input output (MIMO) system for communication in highly mobility scenarios like high speed Railways. As popularity train increasing day by day, data rate wireless is extremely required. 5G systems must be designed to meet requirement broadband services at around 500 km/h, which expected achievable HSR systems, a 180 Mbps or high...

In this paper, commercially-available software-defined radios (SDRs) are used to build a 64-channel, reconfigurable Active Electronically Scanned Arrays (AESA) radar operating in C-band (NATO G-band). The SDRs design and implement 3-dimensional multi-input multi-output (MIMO) radar. flexibility of the has been harnessed evaluate performance linear frequency modulated continuous wave (LFMCW) MIM...
