Quad-LED and Dual-LED Complex Modulation for Visible Light Communication
T. Lakshmi Narasimhan, R. Tejaswi, A. Chockalingam
In this paper, we propose simple and novel complex modulation techniques that exploit the spatial domain to transmit complex-valued modulation symbols in visible light wireless com…
Coded Index Modulation for Non-DC-Biased OFDM in Multiple LED Visible Light Communication
S. P. Alaka, T. Lakshmi Narasimhan, A. Chockalingam
Use of multiple light emitting diodes (LED) is an attractive way to increase spectral efficiency in visible light communications (VLC). A non-DC-biased OFDM (NDC OFDM) scheme that…
Generalized Spatial Modulation in Large-Scale Multiuser MIMO Systems
T. Lakshmi Narasimhan, P. Raviteja, A. Chockalingam
Generalized spatial modulation (GSM) uses transmit antenna elements but fewer transmit radio frequency (RF) chains, . Spatial modulation (SM) and spatial multiplexing…
Generalized Spatial Modulation in Indoor Wireless Visible Light Communication
S. P. Alaka, T. Lakshmi Narasimhan, A. Chockalingam
In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses light emitting di…
