2. 1. Bit-Wise Decoders for Coded Modulation and Broadcast Coded Slotted ALOHA

   Author : Mikhail Ivanov; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mutual information; vehicular communications; bit-interleaved coded modulation; error floor; slotted ALOHA; medium access control; All-to-all broadcast;

   Abstract : This thesis deals with two aspects of wireless communications. The first aspect is about efficient point-to-point data transmission. To achieve high spectral efficiency, coded modulation, which is a concatenation of higher order modulation with error correction coding, is used. READ MORE

4. 2. Robust Vehicular Communications for Traffic Safety---Channel Estimation and Multiantenna Schemes

   Author : Keerthi Nagalapur; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Safety; Sector Antennas; All-to-all Broadcast; Channel Estimation; Cross-layer Pilot Scheme; Multiantenna Schemes; Vehicular Communications V2X ;

   Abstract : Vehicular communications, where vehicles exchange information with other vehicles or entities in the road traffic environment, is expected to be a part of the future transportation system and promises to support a plethora of applications for traffic safety and efficiency. In particular, vehicle-to-vehicle (V2V) communication promises to support numerous traffic safety applications by enabling a vehicle to broadcast its current status to all the other vehicles in its surrounding.

5. 3. Relaying for Timely and Reliable Applications in Wireless Networks

   Author : Le-Nam Hoang; Elisabeth Uhlemann; Magnus Jonsson; Anthony Ephremides; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Many emerging applications based on wireless networks involve distributed control. This implies high requirements on reliability, but also on predictable maximum delay. Further, for applications, it is vital to use off-the-shelf components, both due to cost constraints and requirements on interoperability with existing networks. READ MORE

6. 4. Ultra Wideband: Communication and Localization

   Author : Vijaya Parampalli Yajnanarayana; Peter Händel; Andreas Springer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra Wideband; TOA; Kalman Filter; Localization; Physical Layer Signaling; Location Aware Communication; Compressive Sampling; Sparse Signal Processing; Wireless Sensor Network; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The first part of this thesis develops methods for UWB communication. To meet the stringent regulatory body constraints, the physical layer signaling technique of the UWB transceiver should be optimally designed. READ MORE
