Unfolding for Joint Channel Estimation and Symbol Detection in MIMO Communication Systems
Swati Bhattacharya, K. V. S. Hari, Yonina C. Eldar
This paper proposes a Joint Channel Estimation and Symbol Detection (JED) scheme for Multiple-Input Multiple-Output (MIMO) wireless communication systems. Our proposed method for J…
A Risk Minimization Framework for Channel Estimation in OFDM Systems
Karthik Upadhya, Chandra Sekhar Seelamantula, K. V. S. Hari
We address the problem of channel estimation for cyclic-prefix (CP) Orthogonal Frequency Division Multiplexing (OFDM) systems. We model the channel as a vector of unknown determini…
Low Complexity Joint Estimation of Synchronization Impairments in Sparse Channel for MIMO-OFDM System
Renu Jose, Sooraj K. Ambat, K. V. S. Hari
Low complexity joint estimation of synchronization impairments and channel in a single-user MIMO-OFDM system is presented in this letter. Based on a system model that takes into ac…
Spatial Modulation in Zero-Padded Single Carrier Communication
Rakshith Rajashekar, K. V. S. Hari
In this paper, we consider the Spatial Modulation (SM) system in a frequency selective channel under single carrier (SC) communication scenario and propose zero-padding instead of…
Maximum Likelihood Algorithms for Joint Estimation of Synchronization Impairments and Channel in MIMO-OFDM System
Renu Jose, K. V. S. Hari
Maximum Likelihood (ML) algorithms, for the joint estimation of synchronization impairments and channel in Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing…
Structured Dispersion Matrices from Space-Time Block Codes for Space-Time Shift Keying
Rakshith Rajashekar, K. V. S. Hari, L. Hanzo
Coherent Space-Time Shift Keying (CSTSK) is a recently developed generalized shift-keying framework for Multiple-Input Multiple-Output systems, which uses a set of Space-Time matri…
