Surat ini mencadangkan algoritma suis pembentuk pancaran adaptif untuk sistem berbilang input berbilang masukan (MIMO) yang realistik melalui prototaip. Ia dianalisis dan dikenal pasti bahawa rejim pembentuk pancaran mod tunggal yang tegar sukar untuk mengekalkan prestasi unggul sepanjang masa kerana tiada penyesuaian kepada variasi saluran yang tidak dapat dielakkan dalam amalan. Untuk mengatasi isu praktikal ini, mekanisme pembentukan rasuk sistematik yang dicadangkan disiasat untuk membolehkan pemilihan dinamik antara ralat min kuasa dua minimum dan algoritma rasuk grid-of-rasuk, yang meningkatkan prestasi pautan ke bawah sistem, termasuk pemprosesan dan kadar ralat blok. Faedah prestasi yang ketara dan kebolehlaksanaan yang realistik telah disahkan melalui ujian lapangan dalam rangkaian langsung dan analisis teori. Sementara itu, algoritma suis pembentuk pancaran adaptif boleh digunakan untuk kedua-dua sistem komunikasi selular dupleks pembahagian masa generasi keempat dan kelima menggunakan teknologi MIMO besar-besaran.

Abstract: This letter proposes an adaptive beamforming switch algorithm for realistic massive multiple-input multiple-output (MIMO) systems through prototypes. It is analyzed and identified that a rigid single-mode beamforming regime is hard to maintain superior performance all the time due to no adaption to the inevitable channel variation in practice. In order to cope with this practical issue, the proposed systematic beamforming mechanism is investigated to enable dynamic selection between minimum mean-squared error and grid-of-beams beamforming algorithms, which improves system downlink performance, including throughput and block error rate. The significant performance benefits and realistic feasibility have been validated through the field tests in live networks and theoretical analyses. Meanwhile, the adaptive beamforming switch algorithm is applicable to both fourth and fifth generation time-division duplexing cellular communication system using massive-MIMO technology.

AB - This letter proposes an adaptive beamforming switch algorithm for realistic massive multiple-input multiple-output (MIMO) systems through prototypes. It is analyzed and identified that a rigid single-mode beamforming regime is hard to maintain superior performance all the time due to no adaption to the inevitable channel variation in practice. In order to cope with this practical issue, the proposed systematic beamforming mechanism is investigated to enable dynamic selection between minimum mean-squared error and grid-of-beams beamforming algorithms, which improves system downlink performance, including throughput and block error rate. The significant performance benefits and realistic feasibility have been validated through the field tests in live networks and theoretical analyses. Meanwhile, the adaptive beamforming switch algorithm is applicable to both fourth and fifth generation time-division duplexing cellular communication system using massive-MIMO technology.
