“…On the other hand, no such efficient k-set exists for k R = 4. This way, one can predict accurately all the efficient sets with any set of parameters (n, k, Q) through graphical implementation of Equation (24). Interestingly, no efficient k-set is available below k R = 5 for n = 8 and k R = 10 with n = 16 at M = 2 and…”

“…Earlier, the concept of using variable number of attributes instead of a fixed one for several standard modulation schemes like DM-OFDM, 12 MM-OFDM-IM 11 and many others have been proposed for the purpose of achieving performance benefit up to a certain degree. [18][19][20][21][22][23][24] Both DM-OFDM 12 and MM-OFDM-IM 11 schemes exploit all the available subcarriers with multiple constellation sets, thereby providing poor EE. Generalized version of both the schemes 19,20 were developed with the aim towards acquiring higher SE.…”

“…As the growth profiles of SE and EE with respect to active subcarrier number are inverse in nature, 24 an acceptable trade-off between SE and EE is necessary for optimizing the system performance. In the existing generalized models of index modulated OFDM, 18,23,24 although performance analyses are done in detail, investigation on selection of combination of active subcarrier number to ensure SE improvement over fixed subcarrier activation scheme remains unexplored. One of our main contributions in this work is to form optimum active subcarrier number sets (k-sets) capable of providing best SE versus EE trade-off with optimized error performance.…”

Recently developed trends in wireless communication encounter extremely high surge in data traffic, which makes it inevitable to employ energy efficient techniques to reduce detrimental consequence of carbon emission over society. This concern has motivated us to upgrade our previous work on index and mode modulated orthogonal frequency division multiplexing (IMM‐OFDM) for achieving dual benefits in terms of spectral and energy efficiency. In this paper, we have proposed a generalized index and mode modulated OFDM scheme with variable number of subcarrier activation. Novelty of this generalized scheme is its capability to act as a unified model for classic OFDM and three other benchmark index modulated OFDM schemes along with our previously proposed IMM‐OFDM scheme. This new scheme outperforms those five descendent schemes in terms of energy efficiency and error performance as indicated by simulation results. Spectral efficiency improvement in this scheme is achieved through optimum sets of active subcarrier number, which are determined to gain most optimized trade‐off between spectral and energy efficiency with least detector complexity. This generalized parent scheme can replace individual models of its five descendent schemes and consequently can be considered to be one of the most promising candidates for next generation mobile communication system.

“…Orthogonal frequency division multiplexing with index modulation (OFDM‐IM) is a popular transmission technology. Its energy and spectral efficiencies are superior to those of conventional OFDM, and the technology applies spatial modulation to subcarriers of OFDM systems 1–11 . However, unlike in conventional OFDM technology, not all subcarriers in OFDM‐IM technology are used to transmit data.…”

In this paper, a novel selective mapping (SLM) method is proposed for reducing the peak‐to‐average power ratio (PAPR) of orthogonal frequency division multiplexing with index modulation (OFDM‐IM) systems. In the proposed method, polar codes are used to construct the SLM phase generation mechanism. This systematic structural design is superior to conventional methods in which phases are randomly generated. Moreover, polar codes and Reed–Muller codes are selected to protect the input data of the OFDM‐IM system. The weight distribution of the Reed–Muller codes is then used to determine the location data of the active subcarriers in the OFDM‐IM system, and these data are used to determine the error correction capacity. Simulation results indicated that the PAPR improvement achieved using the proposed method is similar to that achieved with conventional SLM methods. Moreover, linear block codes are used to construct the active subcarrier selection and SLM phase generation mechanisms to ensure that both mechanisms have systematic structural designs.
