  1. 16. Adaptive FEC-Encoding for Video Streaming over WiFi

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Anders Branderud; [2013]
    Keywords : ;

    Abstract : In video streaming it is important that the video stream reaches the users in time, and without errors. To retransmit lost packets in a largescale multimedia video transmission is often unfeasible because of the retransmission delay. READ MORE

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Zhaoyu Wang; [2012]
    Keywords : telemedicine; medical sensor; encoding strategy; streaming protocol;

    Abstract : Telemedicine extends medical services to patients in remote areas. Due to the trend of population ageing, telemedicine becomes more and more popular. The Internet provides great opportunity for transmitting medical data. READ MORE

  4. 18. On Forward Error Correction in IEEE 802.15.4 Wireless Sensor Networks

    University essay from Institutionen för informationsteknologi och medier

    Author : Wei Li; Zhiyuan Guo; [2012]
    Keywords : IEEE 802.15.4 standard; WSN; FEC; HARQ; reliability; energy efficiency;

    Abstract : Wireless Sensor Networks (WSN) are used in many applications, for example industrial applications, automatic control applications, monitoring applications, to name but a few. Although WSN can employ different standards in order to achieve short range wireless communication, the mainstream of the market is toadopt the low-power, low-rate IEEE 802. READ MORE

  5. 19. Error Control in Wireless Sensor Networks : A Process Control Perspective

    University essay from Signaler och System

    Author : Oskar Eriksson; [2011]
    Keywords : wireless sensor networks; process control; hybrid ARQ; forward error correction; FEC; HARQ; adaptive FEC;

    Abstract : The use of wireless technology in the process industry is becoming increasingly important to obtain fast deployment at low cost. However, poor channel quality often leads to retransmissions, which are governed by Automatic Repeat Request (ARQ) schemes. READ MORE

  6. 20. Evaluation of Word Length Effects on Multistandard Soft Decision Viterbi Decoding

    University essay from Elektroniksystem

    Author : Ahmed Salim; [2011]
    Keywords : Soft-Decision Viterbi; Tail-biting; Zero-tail; Direct Trace-back; Word Length effects; floating point quantization; BER analysis;

    Abstract : There have been proposals of many parity inducing techniques like Forward ErrorCorrection (FEC) which try to cope the problem of channel induced errors to alarge extent if not completely eradicate. The convolutional codes have been widelyidentified to be very efficient among the known channel coding techniques. READ MORE
