  1. 1. Machine Intelligence in Decoding of Forward Error Correction Codes

    University essay from KTH/Teknisk informationsvetenskap

    Author : Navneet Agrawal; [2017]
    Keywords : ;

    Abstract : A deep learning algorithm for improving the performance of the Sum-ProductAlgorithm (SPA) based decoders is investigated. The proposed Neural NetworkDecoders (NND) [22] generalizes the SPA by assigning weights to the edges ofthe Tanner graph. We elucidate the peculiar design, training, and working of theNND. READ MORE

  3. 2. 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

  4. 3. Unequal Error Protection for Wireless Imaging

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sandya Rondla; [2009]
    Keywords : UEP; JPEG; ROI; BCH codes; Hamming codes; Gaussian channel; and Rayleigh fading.;

    Abstract : This thesis work was to examine the unequal error protection (UEP) scheme for joint photographic experts group (JPEG) 2000 images over an additive white Gaussian noise (AWGN) and a Rayleigh fading channel. The JPEG 2000 standard provides an effective image compression that result in increasing effect of transmission errors. READ MORE
