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…
Power Allocation in Amplify and Forward Relays with a Power Constrained Relay
Dinesh Dileep Gaurav, K. V. S. Hari
We consider a two-hop Multiple-Input Multiple-Output channel with a source, a single Amplify and Forward relay, and the destination. We consider the problem of designing precoders…
Low Complexity Maximum Likelihood Detection in Spatial Modulation Systems
Rakshith Rajashekar, K. V. S. Hari
Spatial Modulation (SM) is a recently developed low-complexity Multiple-Input Multiple-Output scheme that uses antenna indices and a conventional signal set to convey information.…
ML Decoding Complexity Reduction in STBCs Using Time-Orthogonal Pulse Shaping
Rakshith Rajashekar, K. V. S. Hari
Motivated by the recent developments in the Space Shift Keying (SSK) and Spatial Modulation (SM) systems which employ Time-Orthogonal Pulse Shaping (TOPS) filters to achieve transm…
Modulation Diversity for Spatial Modulation Using Complex Interleaved Orthogonal Design
Rakshith Rajashekar, K. V. S. Hari
In this paper, we propose modulation diversity techniques for Spatial Modulation (SM) system using Complex Interleaved Orthogonal Design (CIOD) meant for two transmit antennas. Spe…
