Overview

The novel transformer model improves signal detection and reduces interference in FTN-RIS MIMO systems, suggesting enhanced data transmission capabilities.

Key Points

  • The proposed transformer model outperforms conventional methods in signal detection within FTN-RIS MIMO systems, improving performance significantly.
  • Achieving a target bit error rate of 10−4, the method exhibits an SNR gain of about 1.5 dB compared to traditional systems.
  • Analyzing the full received signal sequence, the transformer successfully addresses non-linear inter-symbol interference, enhancing signal recovery.
  • Higher spectral efficiency of nearly 2 bps/s/Hz is maintained while effectively reversing detrimental ISI patterns.
