Teknik prapengekodan hibrid (HP) telah dianggap secara meluas sebagai pendekatan yang menjanjikan untuk sistem komunikasi gelombang milimeter. Secara umum, struktur HP sedia ada dengan rangkaian penukar fasa resolusi tinggi yang rumit boleh mencapai kecekapan spektrum yang hampir optimum, namun, ia melibatkan penggunaan tenaga yang tinggi. Seni bina HP dengan rangkaian suis cekap tenaga boleh mengurangkan penggunaan tenaga dengan ketara. Untuk mencapai kecekapan tenaga maksimum, kertas kerja ini memfokuskan pada seni bina HP dengan rangkaian suis dan mempertimbangkan struktur HP rangkaian analog adaptif novel untuk sistem MIMO mmWave sedemikian, yang boleh memberikan potensi keuntungan tatasusunan. Selain itu, algoritma kemas kini koordinat penyesuaian berbilang pengguna dicadangkan untuk masalah reka bentuk HP bagi struktur baharu ini. Hasil simulasi mengesahkan bahawa reka bentuk yang dicadangkan kami boleh mencapai kecekapan tenaga yang lebih baik daripada skim HP lain yang dicadangkan baru-baru ini apabila bilangan pengguna adalah kecil.

Abstract: The hybrid precoding (HP) technique has been widely considered as a promising approach for millimeter wave communication systems. In general, the existing HP structure with a complicated high-resolution phase shifter network can achieve near-optimal spectral efficiency, however, it involves high energy consumption. The HP architecture with an energy-efficient switch network can significantly reduce the energy consumption. To achieve maximum energy efficiency, this paper focuses on the HP architecture with switch network and considers a novel adaptive analog network HP structure for such mmWave MIMO systems, which can provide potential array gains. Moreover, a multiuser adaptive coordinate update algorithm is proposed for the HP design problem of this new structure. Simulation results verify that our proposed design can achieve better energy efficiency than other recently proposed HP schemes when the number of users is small.

AB - The hybrid precoding (HP) technique has been widely considered as a promising approach for millimeter wave communication systems. In general, the existing HP structure with a complicated high-resolution phase shifter network can achieve near-optimal spectral efficiency, however, it involves high energy consumption. The HP architecture with an energy-efficient switch network can significantly reduce the energy consumption. To achieve maximum energy efficiency, this paper focuses on the HP architecture with switch network and considers a novel adaptive analog network HP structure for such mmWave MIMO systems, which can provide potential array gains. Moreover, a multiuser adaptive coordinate update algorithm is proposed for the HP design problem of this new structure. Simulation results verify that our proposed design can achieve better energy efficiency than other recently proposed HP schemes when the number of users is small.
