5. 3. Low Cost Remote Antenna Units in CMOS for Fiber-fed Distributed MIMO Systems

   Author : Waqas Ahmad; Institutionen för elektro- och informationsteknik; []
   Keywords : Remote Antenna Unit; distributed MIMO systems; CMOS technology; power amplifier; linearization; CMOS photodiodes; transimpedance amplifier; radio over fiber; optical communication;

   Abstract : Massive multiple input multiple output (MIMO) is a revolutionary communication technique, where large numbers of antennas are employed at the base stations to increase the spectral efficiency, reliability and data rate of the system. Moreover, in multi-user MIMO (MU-MIMO) multiple users can be served by the base stations on the same time-frequency resource. READ MORE

7. 5. High Capacity Fiber-Connected Wireless MIMO Communication

   Author : Husileng Bao; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; central unit; Radio-over-Fiber; millimeter-wave.; multiple-inputmultiple- output; remote radio head;

   Abstract : There will be more and more users while beyond-5G (B5G) and 6G bring more wireless applications. Current cellular communication networks assign specific serving boundaries for each radio, which becomes a limitation when too many users work with one radio simultaneously. By physically distributing radios. user’s service can be more uniform. READ MORE
