Amplitude and frequency modulation behaviours of cellular neural networks
(2012)
As is well known, Amplitude Modulation (AM) and Frequency Modulation (FM) are the most popular modulation techniques in communications [1]. Classically, they are designed as individual systems at transmitters; however in ...
MP-SAGE based channel estimation for underwater cooperative OFDM systems
(2013)
In this paper, an efficient ehannel estimation algorithm is proposed fOl' amplify-And-forward (AF) eooperative relay based orthogonal fl'equency division multiplexing (OFDM) system in the presenee of sparse underwater ...
A new technique for OFDM: OFDM-index modulation
(2013)
In this study, a novel scheme called orthogonal frequency division multiplexing with index modulation (OFDMIM) is proposed for frequency selective channels. In this scheme, the information is conveyed not only by only M-Ary ...
Performance of MIMO enhanced unipolar OFDM with realistic indoor visible light channel models
(Institute of Electrical and Electronics Engineers Inc., 2016)
Visible light communication (VLC) involves the dual use of illumination infrastructure for high speed wireless access. Designing such optical based communication systems, realistic indoor optical channel modeling becomes ...
