Sistem berbilang input berbilang pembawa tunggal (MIMO) dengan saluran selektif frekuensi mengalami gangguan antara simbol (ISI) dan gangguan saluran bersama (CCI). Untuk menghapuskan kedua-dua jenis gangguan, kami mencadangkan dalam surat ini penyamaan maklum balas keputusan dua peringkat hibrid (HTS-DFE), yang melaksanakan penyamaan domain frekuensi (FDE) pada peringkat pertama dan pembatalan gangguan bersiri bersiri (SIC). ) pada peringkat kedua. Memandangkan seni bina maklum balas keputusan (DF) atau ramalan hingar (NP) boleh digunakan dalam FDE atau SIC, penyamaan yang dicadangkan sebenarnya boleh mempunyai empat variasi yang mencapai ralat min kuasa dua (MSE) yang sama di bawah andaian maklum balas yang sempurna. Selanjutnya, kami menggabungkan HTS-DFE dengan skim maklum balas keputusan yang dinyahkod (DDF) untuk mengurangkan penyebaran ralat yang dihadapi dalam amalan. Keputusan simulasi mengesahkan bahawa HTS-DFE yang dicadangkan boleh mengatasi prestasi penyamaan sedia ada dengan ketara.

Abstract: A single-carrier multiple-input multiple-output (MIMO) system with frequency-selective channels suffers from the inter-symbol interference (ISI) and the co-channel interference (CCI). To eliminate both type of interference, we propose in this letter a hybrid two-stage decision-feedback equalizer (HTS-DFE), which performs the frequency-domain equalization (FDE) in the first stage and the layered serial interference-cancellation (SIC) in the second stage. Since the decision-feedback (DF) or noise-prediction (NP) architecture can be employed in FDE or SIC, the proposed equalizer actually can have four variations that achieve the same mean square error (MSE) under the assumption of perfect feedback. Further, we combine HTS-DFE with the decoded decision-feedback (DDF) scheme to mitigate the error-propagation encountered in the practice. Simulation results confirm that the proposed HTS-DFE can outperform the existing equalizers significantly.
