The paper explores the application of spatial modulation (SM) and space shift keying (SSK) schemes to enhance the spectral efficiency (SE) and bit-error rate (BER) performance of LEO satellite-assisted wireless communication systems.
The key highlights are:
The LEO-SM and LEO-SSK schemes are designed to improve the SE of traditional LEO satellite-assisted MIMO wireless systems. This is the first work to explore the performance of these schemes under imperfect channel state information (CSI).
The analytical performance of SE and detection complexity is presented, revealing interesting insights.
Monte Carlo simulations show the superiority of the proposed schemes in terms of BER performance and SE compared to traditional LEO satellite-assisted schemes. The results also highlight the trade-offs between the LEO-SM and LEO-SSK schemes.
The analysis underscores the potential of both the LEO-SM and LEO-SSK schemes as viable candidates for future 6G LEO satellite-assisted wireless communication systems, offering improved spectral efficiency and reliability.
