1. 1. Optimal Power Allocation and Ergodic Capacity in Cognitive Radio Network

   University essay from KTH/Skolan för elektro- och systemteknik (EES)

   Author : Guanren Wen; [2016]
   Keywords : ;

   Abstract : Cognitive radio network allows the secondary users (SUs) in a secondary communication network (SCN) coexist with priority users in a priority communication network (PCN). The interference caused by SCN to PCN is required to be rational and not affected the quality of server within the PCN to each priority users (PUs). READ MORE

3. 2. Exploiting the Direct Communication Link for Enhancing Effective Capacity Performance of Cognitive Radio Relay Networks

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Md Abdul Matin Biswas; [2014]
   Keywords : Cognitive Radio; Quality of Service QoS ; Effective Capacity; Cooperative Relaying; Cognitive Relay Networks; Peak Interference Power Constraint; Delay QoS Constraint;

   Abstract : Nowadays, cognitive radio (CR) is a promising concept to improve the radio spectrum exploitation. CR has tremendous ability to enhance spectrum efficiency by allowing secondary users (SUs) to access licensed radio spectrum resource which is currently not being used by primary users (PUs).

4. 3. Impact of Interference from Primary User on the Performance of Cognitive Radio Networks

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Maarig Aregawi Hagos; Marshed Mohamed; [2012]
   Keywords : cognitive radio; ergodic capacity; outage probability; SIMO; SINR;

   Abstract : This thesis report presents background knowledge about cognitive radio network (CRN) and investigates performance of underlay cognitive radio networks based on an adaptive power allocation policy of secondary transmitter (SU-Tx). In particular, it has been assumed that SU-Tx and primary user transmitter (PU-Tx) are equipped with a single antenna, while the corresponding receivers are equipped with multiple antennas.

5. 4. Hybrid Power Control in Time Division Scheduling Wideband Code Division Multiplex Access

   University essay from KTH/Kommunikationssystem, CoS

   Author : Zhuo Cheng; [2011]
   Keywords : WCDMA; High-Speed Uplink Packet Access; Power Control; unused code GRAKE;

   Abstract : With high date rates using Enhanced Uplink (EUL), a conventional signal to interference ratio (SIR) based power control algorithm may lead to a power rush due to self interference or incompatible SIR target [2]. Time division (TD) scheduling in Wideband Code Division Multiplex Access (WCDMA) is considered to be a key feature in achieving high user data rates. READ MORE
