Performance Improvement of Dimmable OFDM-Visible Light Communication using Subcarrier Index Modulation and Reed Solomon Encoding

  title={Performance Improvement of Dimmable OFDM-Visible Light Communication using Subcarrier Index Modulation and Reed Solomon Encoding},
  author={Nima Taherkhani and Kamran Kiasaleh},
In this paper, we propose a new subcarrier index modulation scheme for orthogonal frequency division multiplexing (OFDM), which incorporates the Reed-Solomon (RS) encoding in a visible light communication (VLC) system. In this scheme, the incoming bits are first encoded using the RS encoder, then a set of symbols in the resulting RS codeword are punctured, and the remaining symbols are modulated and mapped onto the OFDM subcarriers. This system is referred to as RS-OFDM-IM. Unlike the…

Subcarrier-Index Modulation for Reed Solomon Encoded OFDM-Based Visible Light Communication
The proposed subcarrier-index modulation with Reed Solomon encoded Optical Orthogonal Frequency Division Multiplexing with index modulation (IM-RS-OFDM) scheme offers a better bit error rate performance compared to the conventional coded OFDM-based visible light communication.
Dual-Mode Index Modulation Aided OFDM
A dual-mode OFDM technique is proposed, which is combined with index modulation and enhances the attainable throughput of conventional index-modulation-based OFDM and achieves a considerably better BER performance than other OFDM systems using index modulation, while imposing the same or lower computational complexity.

In this technique, the data is encoded using an RS codeword and part of the redundancy introduced by the frame which exceeds the clipping range are removed by applying different number of puncturing, and the redundancy left in the data are used at the receiver side to retrieve the data block.
On the Achievable Rate of OFDM With Index Modulation
The performance of OFDM-IM is studied in terms of the achievable rate assuming an M-ary constellation and that channel state information is available at the receiver, and an interleaved grouping method is proposed for the use of subcarriers.
Orthogonal Frequency Division Multiplexing With Index Modulation
It is shown via computer simulations that the proposed OFDM with index modulation achieves significantly better error performance than classical OFDM due to the information bits carried by the indices of OFDM subcarriers under both ideal and realistic channel conditions.

A new transmission approach, referred to as subcarrier-index modulation (SIM) is proposed to be integrated with the orthogonal frequency division multiplexing (OFDM) systems, i.e. amplitude shift keying (ASK) and quadrature amplitude modulation (QAM).
Enhanced subcarrier index modulation (SIM) OFDM
A modified technique is proposed which avoids bit error propagation whilst retaining the benefits of the concept and can lead to a decrease of the peak system power, which is highly beneficial in the context of optical wireless communication.
Clipping Noise in OFDM-Based Optical Wireless Communication Systems
The model for clipping noise can be modeled according to the Bussgang theorem and the central limit theorem as attenuation of the data-carrying subcarriers at the receiver and addition of zero-mean complex-valued Gaussian noise to derive the electrical signal-to-noise ratio (SNR).
Subcarrier-Index Modulation Aided OFDM - Will It Work?
These performance investigations identify the beneficial operating region of the SIM scheme over its conventional orthogonal frequency-division multiplexing (OFDM) counterpart, hence providing general design guidelines for the SIM parameters.
Design of Multilevel Reed–Solomon Codes and Iterative Decoding for Visible Light Communication
A joint design of color-shift keying (CSK) constellation and the MRS code, optimizing the decoding performance, is investigated and the proposed IMSD algorithm achieves significant iterative decoding gains.
