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…
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…
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…
Sphere Decoding for Spatial Modulation Systems with Arbitrary Nt
Rakshith Rajashekar, K. V. S. Hari
Recently, three Sphere Decoding (SD) algorithms were proposed for Spatial Modulation (SM) scheme which focus on reducing the transmit-, receive-, and both transmit and receive-sear…
