Baru-baru ini, perkhidmatan penyiaran diperkenalkan dalam rangkaian selular dan kepelbagaian makro ialah cara yang berkesan untuk memerangi pudar. Dalam kertas kerja ini, kami mencadangkan sejenis kod blok ruang-masa (STBC) yang diedarkan untuk kepelbagaian makro yang dibina daripada jumlah antena berbilang stesen pangkalan yang bekerjasama, dan semua antena membentuk sistem keluaran berbilang input berbilang (MIMO) yang setara. Kod ini dinamakan High-Dimension-Full-Rate-Quasi-Orthogonal STBC (HDFR-QOSTBC) yang boleh dicirikan sebagai: (1) Ia boleh digunakan dengan sebarang bilangan antena pemancar terutamanya apabila bilangan antena pemancar adalah besar; (2) Kod adalah dengan kadar penghantaran penuh satu; (3) Kerumitan penyahkodan Kemungkinan Maksimum (ML) kod ini boleh dikawal dan terhad kepada Nt/2-simbol-boleh dinyahkod untuk jumlah Nt menghantar antena. Kemudian, kami menganalisis sepenuhnya struktur saluran setara untuk jenis kod dan mendedahkan sifat bahawa vektor eigen bagi saluran setara adalah malar dan bebas daripada realisasi saluran, dan ciri ini boleh dieksploitasi untuk struktur penghantaran baharu dengan satu- penyahkod linear simbol. Tambahan pula, kami menganalisis skim kepelbagaian makro yang berbeza dan memberikan perbandingan prestasi. Keputusan simulasi menunjukkan bahawa skim yang dicadangkan adalah praktikal untuk sistem penyiaran dengan peningkatan prestasi yang ketara berbanding dengan kaedah gabungan lembut dan kepelbagaian kelewatan kitaran (CDD).

Abstract: Recently, broadcast services are introduced in cellular networks and macro diversity is an effective way to combat fading. In this paper, we propose a kind of distributed space-time block codes (STBCs) for macro diversity which is constructed from the total antennas of multiple cooperating base stations, and all the antennas form an equivalent multiple input multiple output (MIMO) system. This code is termed High-Dimension-Full-Rate-Quasi-Orthogonal STBC (HDFR-QOSTBC) which can be characterized as: (1) It can be applied with any number of transmit antennas especially when the number of transmit antennas is large; (2) The code is with full transmit rate of one; (3) The Maximum Likelihood (ML) decoding complexity of this code is controllable and limited to Nt/2-symbol-decodable for total Nt transmit antennas. Then, we completely analyze the structure of the equivalent channel for the kind of codes and reveal a property that the eigenvectors of the equivalent channel are constant and independent from the channel realization, and this characteristic can be exploited for a new transmission structure with single-symbol linear decoder. Furthermore, we analyze different macro diversity schemes and give a performance comparison. The simulation results show that the proposed scheme is practical for the broadcast systems with significant performance improvement comparing with soft-combination and cyclic delay diversity (CDD) methods.
