What is index modulation (IM)? This is an interesting question that we have started to hear
more and more frequently over the past few years. The aim of this paper is to answer this …

In this paper, a novel orthogonal frequency division multiplexing (OFDM) scheme, called
OFDM with index modulation (OFDM-IM), is proposed for operation over frequency-selective …

Recently, orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-
IM) was proposed. By selecting a fixed number of subcarriers as active subcarriers to carry …

Spatial modulation (SM) is a newly emerging multiple-input-multiple-output technique that
activates only a single antenna for transmission at any time instant and uses the index of the …

Multiple-input multiple-output orthogonal frequency division multiplexing with index
modulation (MIMO-OFDM-IM) is a novel multicarrier transmission technique which has been …

Novel transmit antenna selection techniques are conceived for Spatial Modulation (SM)
systems and their symbol error rate (SER) performance is investigated. Specifically, low …

The main limitations of employing large-scale antenna (LSA) architectures for broadband
frequency-selective channels include, but are not limited to their complexity, power …
