2. 1. 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

4. 2. Millimeter-Wave Photonics: Signal Sources and Transmission Links

   Author : Andreas Wiberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave photonics; mm-wave generation; radio over fiber; photonic frequency multiplication; millimeter-wave photonics; millimeter-waves; millimeter-wave communication system;

   Abstract : With the use of higher and higher frequencies in a number of current and future wireless millimeter-wave applications it is beneficial to use photonics for several reasons. The use of optical fibers is an advantageous way to transport millimeter-waves in terms of loss, mechanical flexibility, weight, and insensitivity to electromagnetic interference. READ MORE

5. 3. High-capacity short-reach optical communications

   Author : Rui Lin; Jiajia Chen; Lena Wosinska; Yu Yu; KTH; []

   Abstract : This thesis deals with the use of photonic technology in microwave and millimeter-wave applications. The two major parts of this work have been techniques for transmission and signal generation. READ MORE

7. 5. Investigation of Sigma-Delta-over-Fiber for High-Capacity Wireless Communication Systems

   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; millimeter-wave; multipleinput- multiple-output; remote radio head; Radio-over-fiber; central unit;

   Abstract : The advent of beyond-5G (B5G) and 6G technologies brings increases in wireless devices and their applications. Although massive multiple-input-multiple-output (MIMO) delivers high-capacity services using co-located MIMO (CMIMO) technology, distributed MIMO (D-MIMO) technology offers a more uniform user service.
