This thesis is devoted to the development of timing recovery techniques for digital recording systems. The thesis begins with a detailed review and discussion of timing recovery structures, requirem...
Abstract— The CRC or cyclic redundancy check is a widely used technique for error checking in many protocols used in data transmission. The main aim of this project is to design the CRC RTL generato...
あらまし センサネットワークでは,多くのセンサノードが密集して配置されることが多く,観測により各セ ンサノードで得られるデータの間には相関がある.このような観測データがフュージョンセンターで収集される ことになる.本論文では,フュージョンセンターでの観測精度について Kullback-Leibler (KL) 情報量の観点か ら検討を行う.特に,KL 情報量すなわち観測精度を劣化させる要因として,...

— We present methods to compute confidence intervals for the codeword error rate (CWER) and bit error rate (BER) of a coded communications link. We review several methods to compute exact and approxim...
–Generalized low-density parity-check (GLDPC) codes, where single parity-check (SPC) constraint nodes are replaced with generalized constraint (GC) nodes, are a promising class of codes for low latenc...
—In this paper a robust, spatial domain watermarking scheme using simple error control coding technique is proposed. The idea of this scheme is to embed an encoded watermark using (5,1) repetition co...
|In this work we studied the performance of the hybrid type-II Automatic Repeat reQuest (ARQ) system on Rayleigh fading channels. This system is based on High Rate Optimized Rate Compatible Punctured ...
|In this paper we present a way to regard the combined face detection and facial feature extraction problem as an optimization problem. This problem is of too high computational complexity to be of pr...
{ To support multimedia applications, future PCS networks will likely involve an advanced interconnected wireless and wireline network. This paper focuses on how a PCS network can compensate for and m...
