Skema Transmit Beamforming untuk Massive MIMO
Abstrak
Teknologi Nirkabel dan mobile menghadapi berbagai tantangan dalam bentuk keterbatasan spectrum komunikasi, peningkatan pengguna dll. Transmit Beamforming dan Massive MIMO merupakan teknologi yang dapat mengatasi tantangan tersebut . Penelitian mengenai skema transmit beamforming pada Massive MIMO belum banyak ditemui. Pada paper ini dibahas bagaimana performansi skema Transmit Beamforming untuk system Massive MIMO. Performansi BER disimulasikan untuk dua kondisi yaitu Massive MIMO (8, 10 dan 12 antena) dan MIMO konvensional (2 antena). Hasil simulasi menunjukkan bahwa performansi BER untuk Massive MIMO dengan skema Transmit Beamforming jauh melampaui skema lainnya.Referensi
