IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY 2025年 第2期74卷 3463-3467页
作者: He, Xin Gong, Yi Huang, Lei Wang, Jiangzhou Shantou Univ Coll Elect & Informat Engn Shantou 515063 Peoples R China Southern Univ Sci & Technol Dept Elect & Elect Engn Shenzhen 518055 Peoples R China Shenzhen Univ State Key Lab Radio Frequency Heterogeneous Integr Shenzhen 518060 Peoples R China Univ Kent Sch Engn Canterbury CT2 7NZ England
To compensate for the severe pathloss in satellite broadcasting system, the phased array with a half wavelength aperture is the conventional scheme. However, it is difficult to further scale up the phased array to pro... 详细信息

IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY 2024年 第7期73卷 10783-10787页
作者: He, Xin Huang, Lei Wang, Jiangzhou Gong, Yi Shantou Univ Coll Elect & Informat Engn Shantou 515063 Peoples R China Shenzhen Univ State Key Lab Radio Frequency Heterogeneous Integr Shenzhen 518060 Peoples R China Univ Kent Sch Engn Canterbury CT2 7NZ England Southern Univ Sci & Technol Dept Elect & Elect Engn Shenzhen 518055 Peoples R China
Owing to the manually fixed step size, the conventional gradient projection (GP) method requires relatively long time to solve the reconfigurable intelligent surface (RIS) aided hybrid beamforming problem. In order to... 详细信息
