Pembentukan pancaran analog dengan tatasusunan antena jalur lebar berskala besar dalam sistem keluaran berbilang input (MIMO) gelombang milimeter (mmWave) menghadapi masalah juling pancaran. Dalam makalah ini, kami mula-mula menyiasat sensitiviti pembentukan rasuk analog kepada pemisahan ruang subarray dalam sistem mmWave jalur lebar menggunakan tatasusunan hibrid, dan mencadangkan pemisahan subarray yang dioptimumkan. Kami kemudiannya mereka bentuk pancaran analog yang lebih baik selepas pampasan fasa berdasarkan jujukan Zadoff-Chu (ZC) untuk meratakan tindak balas frekuensi saluran setara frekuensi radio (RF). Memandangkan skim penyamaan domain frekuensi-pembawa tunggal (SC-FDE) pada penerima, kami memperoleh penyamaan sifar paksaan (ZF) linear kerumitan rendah dan ralat kuasa dua minimum (MMSE) dari segi nisbah isyarat-ke-bunyi keluaran (SNR) selepas penyamaan. Keputusan simulasi menunjukkan bahawa pembentuk pancaran analog yang dipertingkatkan dengan berkesan boleh menghilangkan kelunturan dalam selektif frekuensi yang disebabkan oleh juling rasuk, dan mencapai prestasi kadar ralat bit yang lebih baik berbanding dengan pembentukan pancaran analog konvensional.

Abstract: Analog beamforming with broadband large-scale antenna arrays in millimeter wave (mmWave) multiple input multiple output (MIMO) systems faces the beam squint problem. In this paper, we first investigate the sensitivity of analog beamforming to subarray spatial separations in wideband mmWave systems using hybrid arrays, and propose optimized subarray separations. We then design improved analog beamforming after phase compensation based on Zadoff-Chu (ZC) sequence to flatten the frequency response of radio frequency (RF) equivalent channel. Considering a single-carrier frequency-domain equalization (SC-FDE) scheme at the receiver, we derive low-complexity linear zero-forcing (ZF) and minimum mean squared error (MMSE) equalizers in terms of output signal-to-noise ratio (SNR) after equalization. Simulation results show that the improved analog beamforming can effectively remove frequency-selective deep fading caused by beam squint, and achieve better bit-error-rate performance compared with the conventional analog beamforming.
