A novel generalized polarization-space modulation (GPSM) is proposed for polarized
multiple-input multiple-output (MIMO) systems with a limit number of radio frequency (RF) …

This paper develops a non-coherent index modulation (IM) system in which activation
patterns are characterized by multi-level block codes. We analyze performance of such a …

In this paper, we propose a simple yet powerful mapping scheme that converts any
conventional square-matrix-based differential space-time coding (DSTC) into a nonsquare …

This paper generalizes the conventional noncoherent OFDM-IM systems by allowing
selection of different numbers of active subcarriers for message representation. We then …

In this letter, a novel forgetting factor aided rectangular differential (RD) orthogonal
frequency division multiplexing (OFDM) with index modulation (IM) is proposed for …

The reconfigurable intelligent surface (RIS) aided index modulation (IM) is a promising
technology for next-generation wireless communications. However, acquiring channel state …

This letter explores the concept of non-coherent index modulation (IM) in a general setting
from the standpoint of coding theory. In doing so, we establish a bijective mapping from the …

Orthogonal Frequency Division Multiplexing (OFDM) with Index Modulation (OFDM-IM),
which conveyed information bits via the activated indices and constellation symbols is a …

Phase modulation has played a crucial role in rendering constant envelope orthogonal
frequency division multiplexing (CE-OFDM) an appealing waveform, characterized by its 0 …

Short packet transmission is a key ingredient for the Internet-of-Things (IoT) communications
that require extremely low latency. The pilot-based short packet transmission makes lower …
