  1. 1. Investigating the Effect of Antenna Polarization on the Performance of CoMP Systems based on Synchronous Multi-link Measurements

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sakib- Bin- Redhwan; Ahmad Shekhan; [2016]
    Keywords : CoMP; MU-MIMO; Sum-rate Capacity; Beamforming; Technology and Engineering;

    Abstract : In this master thesis work, the effect of polarization, at the Base Station (BS) side, on the performance of multi-user Coordinated Multipoint (CoMP) systems is studied. This study was performed using synchronous multi-link measurements that took place at the campus of the faculty of Engineering, LTH, Lund University, Lund, Sweden, where two different BS setups were studied.

  3. 2. 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

  4. 3. Capacity Analysis of Cognitive Radio Relay Networks under Transmission and Interference Power Constraints

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Abhijith Gopalakrishna; [2012]
    Keywords : effective capacity; outage capacity; ergodic capacity; cognitive radio; relay networks;

    Abstract : This thesis investigates the performance of cognitive radio relay networks (CRRN) in Rayleigh fading channel under various power constraints. Here spectrum sharing approach is considered, whereby a secondary user (SU) may be allowed to transmit simultaneously with a primary user (PU) as long as SU interference to PU remains below a tolerable level.

  5. 4. 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.

  6. 5. Root LDPC Codes for Non Ergodic Transmission Channels

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Tarique Inayat Bhutto; [2011]
    Keywords : Non-Binary Root LDPC codes; LDPC codes; Binary-Root LDPC codes;

    Abstract : 4 ABSTRACT Tremendous amount of research has been conducted in modern coding theory in the past few years and much of the work has been done in developing new coding techniques. Low density parity check (LDPC) codes are class of linear block error correcting codes which provide capacity performance on a large collection of data transmission and storage channels while Root LDPC codes in this thesis work are admitting implementable decoders with manageable complexity.
