Antena tatasusunan suai perlu digunakan untuk penindasan CCI dalam domain spatial. Walau bagaimanapun, antena tatasusunan suai mempunyai beberapa masalah seperti berikut. Oleh kerana antena tatasusunan suai mengambil masa yang lama untuk menumpu kepada berat antena yang optimum, sukar untuk dikesan sekiranya saluran berubah-ubah dengan cepat. Sebaliknya, beban pemprosesan bertambah dengan bilangan elemen dalam antena tatasusunan. Untuk menyelesaikan masalah ini, kami mencadangkan antena tatasusunan menggunakan antena tatasusunan sebagai antena elemen, yang dipanggil "Antena tatasusunan berlapis." Pada lapisan 1, kawasan sektor ditentukan. Kita boleh menukar kawasan sektor mengikut taburan DOA, kerana kawasan sektor ditentukan oleh berat antena. Pada lapisan ke-2, MMSE dilakukan. Gangguan yang tidak dapat ditindas pada lapisan pertama ditindas pada lapisan ke-1. Dengan sistem yang dicadangkan, kami mengesahkan kelajuan penumpuan yang lebih tinggi sambil melegakan kerumitan pemprosesan.

Abstract: An adaptive array antenna should be applied for suppression of CCI in the spatial domain. However, the adaptive array antenna has some problems as follows. Because the adaptive array antenna takes a long time to converge to the optimum antenna weights, it's hard to track in case of quick varying channel. On the other hand, processing burden increases with the number of elements in the array antenna. To solve these problems, we propose an adaptive array antenna using array antenna as element antennas, the so-called "Layered array antenna." At the 1st layer, sector area are defined. We can change the sector areas according to the DOA distribution, because the sector areas are defined by the antenna weights. At the 2nd layer, MMSE is performed. Interference that couldn't be suppressed at the 1st layer is suppressed at the 2nd layer. By the proposed system, we confirmed higher convergence speed while relieving processing complexity.
