Surat ini mengembangkan Interferometri Pembawa Resolusi Masa Tinggi (HTRCI) yang dicadangkan sebelum ini untuk menganggarkan lebih banyak maklumat status saluran (CSI). HTRCI adalah berdasarkan simbol perintis jenis sikat pada OFDM dan CSI untuk subcarrier nol diinterpolasi oleh pemprosesan isyarat domain masa. Untuk menggunakan subpembawa perintis nol sedemikian untuk meningkatkan CSI yang boleh dianggarkan, ia secara amnya harus dipisahkan dalam domain frekuensi sebelum proses anggaran dan interpolasi. Cadangan utama ialah skim pemisahannya bersempena dengan rawatan HTRCI domain temporal. Keberkesanannya disahkan oleh penyahcemaran perintis pada senario penghantaran MIMO dua sel pautan bawah. Prestasi kadar ralat binari (BER) boleh dipertingkatkan berbanding HTRCI konvensional dan padding sifar (ZP) yang menggantikan alias tindak balas impuls dengan sifar.

Abstract: This letter expands the previously proposed High Time Resolution Carrier Interferometry (HTRCI) to estimate a larger amount of channel status information (CSI). HTRCI is based on a comb-type pilot symbol on OFDM and CSI for null subcarriers are interpolated by time-domain signal processing. In order to utilize such null pilot subcarriers for increasing estimable CSI, they should generally be separated in frequency-domain prior to estimation and interpolation processes. The main proposal is its separation scheme in conjunction with the HTRCI treatment of the temporal domain. Its effectiveness is verified by a pilot de-contamination on downlink two-cell MIMO transmission scenario. Binary error rate (BER) performance can be improved in comparison to conventional HTRCI and zero padding (ZP) which replaces the impulse response alias with zeros.
