Dalam makalah ini, saluran geganti berbilang input berbilang-output (MU-MIMO) disiasat, di mana nod sumber menyediakan berbilang rasuk kepada berbilang pengguna melalui nod geganti berbilang antena. Dalam senario ini, matriks pemprosesan linear pada nod geganti direka bentuk sekitar skema pepenjuru blok (BD) untuk meningkatkan kadar jumlah sistem. Berbanding dengan matriks pemprosesan linear tradisional dengan skema pemaksaan sifar (ZF) pada nod geganti, matriks yang dicadangkan berdasarkan skema BD bukan sahaja dapat menghapuskan gangguan berbilang pengguna pada tahap yang sama seperti skema ZF, tetapi juga merealisasikan kuasa optimum. peruntukan pada nod geganti. Simulasi berangka menunjukkan skema BD mengatasi skema ZF dan boleh meningkatkan prestasi kadar jumlah dengan ketara.

Abstract: In this paper, the multi-user multiple-input multiple-output (MU-MIMO) relay channel is investigated, where the source node provides multi-beams to multi-users via a multi-antenna relay node. In this scenario, linear processing matrix at the relay node is designed around block diagonal (BD) scheme to improve the system sum-rate. Compared with the traditional linear processing matrix with zero-forcing (ZF) scheme at the relay node, the proposed matrix based on BD scheme can not only eliminate the multi-user interference to the same extent as the ZF scheme, but also realize optimal power allocation at the relay node. Numerical simulations demonstrate the BD scheme outperforms the ZF scheme and can significantly improve the sum-rate performance.
