TL;DR: The next few pages will deal with the detailed study of wireless cellular technologies—first, second, third, and fourth generations eventually leading to the fifth generation as well, which will visualize the evolution from analog system transmissions to digital transmissions which brought the usage of audio, graphics, video, etc.
Abstract: Development of mobile communication is rapid, with different methods and techniques being introduced in wireless communications. The next few pages will deal with the detailed study of wireless cellular technologies—first, second, third, and fourth generations eventually leading to the fifth generation as well. This will visualize the evolution from analog system transmissions to digital transmissions which brought the usage of audio, graphics, video, etc. The evolution also gave rise to Internet on the cellular mobile phones which were once realizable only in computers through broadband connections. With improved technologies, we saw the development of fourth-generation cell phones which harnessed the use of LTE. The world is moving very fast, and the corporates involved in mobile communications are in a strong tussle to achieve the fifth generation of mobile networks which will shift the world’s entire way of functioning from autonomous vehicles to IoT and many other things which could be seen only as part of sci-fi movies.

TL;DR: The proposed manuscript presents a benchmarking model for addressing the issues associated with Best-Channel Quality Indicator, Round Robin, and Hybrid Automatic Repeat Request (HARQ) and the outcome shows HARQ scheduling to offer better performance in higher throughput, higher fairness, and lower delay over different test cases.
Abstract: Downlink scheduling is one of the essential operations when it comes to improving the quality of service in Long Term Evolution (LTE) With an increasing user base, there will be an extensive challenge in resource provisioning too A review of existing approaches shows that there is a significant possibility of improvement in this regard, and hence, the proposed manuscript presents a benchmarking model for addressing the issues associated with Best-Channel Quality Indicator (CQI), Round Robin, and Hybrid Automatic Repeat Request (HARQ) The outcome shows HARQ scheduling to offer better performance in higher throughput, higher fairness, and lower delay over different test cases

TL;DR: In this paper , a wireless analog feedback communication system (AFCS) using a Rayleigh fading channel is considered in forward transmission while AWGN was considered in the feedback channel and the performance of the system was evaluated based on the minimization of mean square error (MSE) at the receiver.
Abstract: In this work, we mathematically model a wireless Analog feedback communication system (AFCS) using a Rayleigh fading channel. AFCS system is a new research area and has promising applications, especially in low-power devices such as sensors. Compared to AWGN, Rayleigh fading channel more closely models the real wireless environment. In this work, AFCS Rayleigh fading channel is considered in forward transmission while AWGN is considered in the feedback channel. We evaluated the performance of the system which is mostly based on the minimization of mean square error (MSE) at the receiver. Even in presence of a wireless fading environment, the AFCS attains a 0 MSE value in 2-3 iterations if a noise power of 10dB is considered while in 10-15 iterations if a noise power of 20dB is considered.
