  1. 26. Channel estimation in mobile wireless systems

    University essay from KTH/Signalbehandling

    Author : Pazi Alli Idd; [2012]
    Keywords : Time-variant channel; Discrete Prolate Spheroidal Sequences DPSS ;

    Abstract : The demands of multimedia services from mobile user equipment (UE) for achieving high data rate, high capacity and reliable communication in modern mobile wireless systems are continually ever-growing. As a consequence, several technologies, such as the Universal Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project (3GPP), have been used to meet these challenges.

  2. 27. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Hassan Sajjad; Muhammad Jamil; [2012]
    Keywords : Signal Processing; Fading Channel; Multi-hop;

    Abstract : This work examines error rate performance of Multi-Hop communication systems, employing Single Input Single Output (SISO) transmissions over Nakagami-m fading channel. Mobile multi-hop relaying (MMR) system has been adopted in several Broadband Wireless Access Networks (BWAN) as a cost-effective means of extending the coverage and improving the capacity of these wireless networks.

  3. 28. Spectrum Selection Technique to Satisfy the QoS Requirements in Cognitive Radio Network

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Sheikh Fakhar Uddin; Ismail Khan Khattak; [2012]
    Keywords : Cognitive Radio Network; QoS; Spectrum Selection ;

    Abstract : The demand of wireless spectrum is increasing very fast as the field of telecommunication is advancing rapidly. The spectrum was underutilized because of fixed spectrum assignment policy and this valuable spectrum can be utilized efficiently by cognitive radio technology. READ MORE

  4. 29. Estimating the frequency response of a receiver : Blind identification

    University essay from Akademin för teknik och miljö

    Author : Deyue Yu; [2012]
    Keywords : ;

    Abstract : Consider a receiver that has an unknown impulse response in the form of linear time-invariant system, which is driven by an input signal and random noise with an unknown distribution. If the unknown impulse response of the receiver could be identified, then its equivalent frequency response can be used for calibration, using deconvolution aiming to regain the original signal under measurement.

  5. 30. 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. READ MORE
