  1. 1. On error-robust source coding with image coding applications

    University dissertation from Stockholm : Signaler, sensorer och system

    Author : Tomas Andersson; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source coding; channel coding; joint source-channel coding; multiple description coding; image coding; vector quantization; channel optimized vector quantization; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Abstract : This thesis treats the problem of source coding in situations where the encoded data is subject to errors. The typical scenario is a communication system, where source data such as speech or images should be transmitted from one point to another. A problem is that most communication systems introduce some sort of error in the transmission. READ MORE

  2. 2. Wireless Broadcasting with Network Coding

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lu Lu; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless broadcasting; relay-aided system; systematic binary deterministic rateless codes; random network coding; instantaneously decodable network coding;

    Abstract : Wireless digital broadcasting applications such as digital audio broadcast (DAB) and digital video broadcast (DVB) are becoming increasingly popular since the digital format allows for quality improvements as compared to traditional analogue broadcast. The broadcasting is commonly based on packet transmission. READ MORE

  3. 3. Link Reliability in Cooperative Relaying Using Network Coding

    University dissertation from Stockholm : KTH

    Abstract : Demand for high data rates is increasing rapidly for future wireless systems.This trend is due to the increase in the number of mobile subscribers that need bandwidth hungry multimedia applications anywhere, anytime. Fourth generation cellular systems like IMT-advanced are being developed to meet these requirements. READ MORE

  4. 4. Smart Cooperation with Network Coding in Hierarchical Wireless Networks

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Nan Li; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communications; Hierarchical networks; 5G; Cognitive radio; Internet of Things; Cooperative communications; Spectrum sharing; Network coding; Optimization; Performance analysis.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : To achieve more dynamic, efficient and intelligent use of the scarce wireless spectrum resource, the concept of cooperation has been formalized into several hierarchical network models in future mobile networks. Cooperative communications, such as relaying, can potentially increase communication efficiency and spectrum utilization due to the broadcast nature of wireless networks, and may lead to a better support for diverse communication modes with flexible spectrum sharing.

  5. 5. Source-channel coding for closed-loop control

    University dissertation from Stockholm : Elektrotekniska system

    Author : Lei Bao; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; joint source--channel coding; source-channel coding; joint coding and control; certainty equivalence; linear quadratic control; stochastic control; wireless sensor network; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Abstract : Networked embedded control systems are present almost everywhere. A recent trend is to introduce wireless sensor networks in these systems, to take advantage of the added mobility and flexibility offered by wireless solutions. In such networks, the sensor observations are typically quantized and transmitted over noisy links. READ MORE
