Space-Time Channel Modulation

TL;DR

This paper introduces space-time channel modulation (STCM), a novel extension of space-time coding that incorporates channel states as a third dimension, leading to improved error performance and flexible trade-offs.

Contribution

The paper proposes three new STCM schemes that extend classical space-time coding into channel states, enhancing performance and offering diverse complexity and data rate options.

Findings

STCM schemes outperform existing media-based modulation in error performance

Proposed schemes offer favorable trade-offs between complexity and data rate

Simulation results validate the effectiveness of the new STCM methods

Abstract

In this paper, we introduce the concept of space-time channel modulation (STCM), which extends the classical space-time block codes into a new third dimension: channel states (transmission media) dimension. Three novel STCM schemes, which provide interesting trade-offs among decoding complexity, error performance and data rate, are proposed. It is shown via computer simulations that the proposed STCM schemes achieve considerably better error performance than the existing media-based modulation (MBM) and classical systems.
