In this article, we propose a deep learning (DL) model to estimate the channel matrix for massive multi-input multi-output (MIMO) system with one-bit analog-to-digital converter (ADC). literature, various DL methods were proposed matrix; however, they limited small range of noise levels. We are driven break data appropriately so that estimation performance improves signal-to-noise ratio (SNR) because primary premise is should perform better in case higher SNR. suggested breaking received...
The next generation of mobile networks is predicted to deliver high data speeds, lower latency, and increase the spectral energy efficiency wireless communication systems. Several technologies are being investigated for usage in 5G networks. Massive multiple-input multiple-output (mMIMO) systems one most promising enabling 5G. Even after recent advancements research, numerous challenges still exist channel estimation mMIMO In context pilot contamination feedback overhead, this study tracks...
As a critical enabler for beyond fifth-generation (B5G) technology, millimeter wave (mmWave) beamforming mmWave has been studied many years. Multi-input multi-output (MIMO) system, which is the baseline operation, rely heavily on multiple antennas to stream data in wireless communication systems. High-speed applications face challenges such as blockage and latency overhead. In addition, efficiency of mobile systems severely impacted by high training overhead required discover best vectors...
THz band enabled large scale massive MIMO (M-MIMO) is considered as a key enabler for the 6G technology, given its enormous bandwidth and low latency connectivity. In large-scale M-MIMO configuration, enlarged array aperture small wavelengths of results in an amalgamation both far field near paths, which makes tasks such channel estimation highly challenging. Moreover, at transceiver, radio frequency (RF) impairments phase noise (PN) analog devices also leads to degradation performance....
Millimeter-wave (mmWave) communications are potential technology for modern 5G wireless personal area networks (WPANs). As the number of wirelessly connected devices increases, need a high data transfer rate can be supplemented by centralized control and directional transmission. However, communication at 60 GHz poses different challenges, including propagation loss, interference management, anti-blockage, spatial reuse, resource allocation. Addressing these issues requires much attention...
