Relay, yang menjanjikan untuk meningkatkan prestasi rangkaian komunikasi masa hadapan, adalah salah satu teknik yang paling menjanjikan untuk sistem IMT-Advanced. Dalam kertas ini, saluran geganti berbilang input berbilang keluaran (MIMO) berdasarkan ukuran luar disiasat. Kami memberi tumpuan kepada pautan antara stesen pangkalan (BS) dan stesen geganti (RS) serta pautan antara RS dan stesen mudah alih (MS). Pertama sekali, saluran diukur menggunakan pembunyi saluran masa nyata dalam jalur frekuensi IMT-Advanced (2.35 GHz dengan lebar jalur 50 MHz). Kemudian, parameter komponen berbilang laluan (MPC) diekstrak menggunakan algoritma jangkaan umum berselang-seli ruang. Parameter MPC kedua-dua pautan dianalisis dan dibandingkan secara statistik. Polarisasi dan statistik spatial diperolehi. Trend spektrum azimut kuasa (PAS) dan diskriminasi polarisasi silang (XPD) dengan pemisahan antara RS dan MS disiasat. Berdasarkan PAS, mekanisme penyebaran senario line-of-sight dan non-line-of-sight dianalisis. Tambahan pula, anggaran bentuk tertutup bagi korelasi saluran diperolehi. Kesan PAS dan XPD terhadap korelasi saluran dikaji. Akhir sekali, beberapa garis panduan untuk konfigurasi antena BS, RS dan MS dibentangkan. Hasilnya mendedahkan ciri-ciri saluran geganti yang berbeza dan menyediakan asas untuk penggunaan praktikal sistem geganti.

Abstract: Relay, which promises to enhance the performance of future communication networks, is one of the most promising techniques for IMT-Advanced systems. In this paper, multiple-input multiple-output (MIMO) relay channels based on outdoor measurements are investigated. We focus on the link between the base station (BS) and the relay station (RS) as well as the link between the RS and the mobile station (MS). First of all, the channels were measured employing a real-time channel sounder in IMT-Advanced frequency band (2.35 GHz with 50 MHz bandwidth). Then, the parameters of multipath components (MPCs) are extracted utilizing space-alternating generalized expectation algorithm. MPC parameters of the two links are statistically analyzed and compared. The polarization and spatial statistics are gotten. The trends of power azimuth spectrum (PAS) and cross-polarization discrimination (XPD) with the separation between the RS and the MS are investigated. Based on the PAS, the propagation mechanisms of line-of-sight and non-line-of-sight scenarios are analyzed. Furthermore, an approximate closed-form expression of channel correlation is derived. The impacts of PAS and XPD on the channel correlation are studied. Finally, some guidelines for the antenna configurations of the BS, the RS and the MS are presented. The results reveal the different characteristics of relay channels and provide the basis for the practical deployment of relay systems.
