21. The Effect of Radio Channel Modelling on the Network Performance in VANET
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Research in vehicle-to-vehicle communication and the Vehicular Ad Hoc Network (VANET) are two major fields of growing interest. The advent and recent development of these concepts foster evolution of the new paradigm of the transportation system, widely known as Intelligent Transport System (ITS). READ MORE

22. Exploiting the Direct Communication Link for Enhancing Effective Capacity Performance of Cognitive Radio Relay Networks
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : 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).

23. The Performance of Dual-Hop Decode-and-Forward Underlay Cognitive Relay Networks with Interference Power Constraints over Weibull Fading Channels
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : With the rapid development and the increasing use of wireless devices, spectrum scarcity has become a problem. The higher frequencies have bad propagation characteristics and the lower frequencies have low data rates, therefore the radio spectrum that is available for efficient wireless transmission is a limited resource.

24. Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions
University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystemAbstract : In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. READ MORE

25. MIMO Channel Equalization and Symbol Detection using Multilayer Neural Network
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : In recent years Multiple Input Multiple Output (MIMO) systems have been employed in wireless communication systems to reach the goals of high data rate. A MIMO use multiple antennas at both transmitting and receiving ends. These antennas communicate with each other on the same frequency band and help in linearly increasing the channel capacity.
