Dihalang oleh kualiti perkhidmatan (QoS), reka bentuk transceiver yang teguh dicadangkan untuk saluran gangguan berbilang input berbilang output (MIMO) dengan maklumat keadaan saluran tidak sempurna (CSI) di bawah model ralat terhad. Pengukuran QoS diwakili sebagai nisbah isyarat-ke-gangguan-tambah-bunyi (SINR) untuk setiap pengguna dengan aliran data tunggal. Masalahnya dirumuskan sebagai pengurangan kuasa jumlah untuk mengurangkan jumlah penggunaan kuasa untuk kecekapan tenaga. Secara berpusat, pengoptimuman berselang-seli dilakukan pada setiap nod. Untuk pemancar tetap, ungkapan bentuk tertutup untuk vektor pembentuk pancaran disimpulkan. Dan untuk penerima tetap, masalah pengecilan jumlah kuasa disusun semula sebagai bentuk atur cara separa pasti dengan kekangan ketaksamaan matriks linear. Keputusan simulasi menunjukkan penumpuan dan keteguhan algoritma yang dicadangkan, yang penting untuk aplikasi praktikal dalam rangkaian wayarles masa hadapan.

Abstract: Constrained by quality-of-service (QoS), a robust transceiver design is proposed for multiple-input multiple-output (MIMO) interference channels with imperfect channel state information (CSI) under bounded error model. The QoS measurement is represented as the signal-to-interference-plus-noise ratio (SINR) for each user with single data stream. The problem is formulated as sum power minimization to reduce the total power consumption for energy efficiency. In a centralized manner, alternating optimization is performed at each node. For fixed transmitters, closed-form expression for the receive beamforming vectors is deduced. And for fixed receivers, the sum-power minimization problem is recast as a semi-definite program form with linear matrix inequalities constraints. Simulation results demonstrate the convergence and robustness of the proposed algorithm, which is important for practical applications in future wireless networks.
