1. 21. LTE UPLINK MODELLING AND ANALYSIS OF CARRIER FREQUENCY OFFSET ON UPLINK TRANSMISSION INTERFERENCE

   University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : Johnson Baby; [2013]
   Keywords : LTE uplink modelling; Carrier frequency offset on LTE uplink;

   Abstract : This master thesis analyzes the effect of Carrier Frequency Offsets (CFO) on LTEuplink transmission, which is the main cause of ICI (Inter Carrier Interference) andMAI (Multiuser Access Interference). A model of the LTE uplink is required toconduct the study and is implemented in MATLAB, in compliance with 3GPPspecifications. READ MORE

3. 22. Adaptive Speech enhancement system using Linear Microphone-array for noise Reduction

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Jeevan Reddy Yarragudi; [2012]
   Keywords : Speech enhancement; Beam former; Generalized side lobe canceler; LMS algorithm ;

   Abstract : A major part of the interaction between humans takes place via speech communication. It is very difficult to understand speech signals in presence of background noise for the normal listeners and hearing impaired persons. The human speech and hearing organ is inherently sensitive to interfering noise. READ MORE

4. 23. 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.

5. 24. 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. 25. Close talk Speech enhancement in Linear Microphone array for Laptop application

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Pardhasaradhi Reddy Cherukula; [2012]
   Keywords : Speech enhancement; Generalized sidelobe canceller; Wiener beamformer; Normalized least mean square algorithm.;

   Abstract : Now a day’s communication through laptops is drastically increasing in numerous fields. During the communication between person to person through laptops the speech signals is contaminated by the other speech interference signals. READ MORE
