On The Capacity of Low-Rank Dyadic Fading Channels in the Low-SNR Regime
Kamal Singh
We characterize the capacity of a low-rank wireless channel with varying fading severity at low signal-to-noise ratios (SNRs). The channel rank deficiency is achieved by incorporat…
Capacity and Performance Analysis of RIS-Assisted Communication Over Rician Fading Channels
Chandradeep Singh, Chia-Hsiang Lin, Kamal Singh
This paper investigates two performance metrics, namely ergodic capacity and symbol error rate, of mmWave communication system assisted by a reconfigurable intelligent surface (RIS…
Low SNR Capacity of Keyhole MIMO Channel in Nakagami-m Fading With Full CSI
Kamal Singh, Chandradeep Singh, Kuang-Hao Liu
In this paper, we obtain asymptotic expressions for the ergodic capacity of the keyhole multiple-input multiple-output (MIMO) channel at low signal-to-noise ratio (SNR) in independ…
Fast Beam Training for RIS-Assisted Uplink Communication
Chandradeep Singh, Kamal Singh, K. H. Liu
In this work, we propose a beam training codebook for Reconfigurable Intelligent Surface (RIS) assisted mmWave uplink communication. Beam training procedure is important to establi…
Optimal Power Control in Decentralized Gaussian Multiple Access Channels
Kamal Singh
We consider the decentralized power optimization problem for Gaussian fast-fading multiple access channel (MAC) so that the average sum-throughput is maximized. In our MAC setup, e…
