RANCANG BANGUN SPREAD SPECTRUM DENGAN METODE SINKRONISASI SERIAL CORRELATOR BERBASIS FPGA

Low Power Parallel Spread-Spectrum Correlator

David Garrett and Mircea Stan [email protected], [email protected] University of Virginia, Department of Electrical Engineering AbstractDirect Sequence Spread Spectrum (DSSS) transmissions require a despreading stage within the standard receiver block to recover the spread spectrum signal. For long spread spectrum codes, the correlation block can be a large portion of the receiver size, he...

Low Power Analog Correlator for Spread Spectrum Time Domain Reflectometry

Analog correlation is an important analog signal processing function. A new analog correlator circuit for implementing Spread Spectrum Time Domain Reflectometry (SSTDR) technique is proposed. SSTDR technique, makes locating intermittent faults possible, by continuously testing live wiring networks. The proposed correlator circuit is more linear by almost an order of magnitude and consumes half ...

Spread Spectrum Watermarking: Implementation in FPGA

Spread spectrum (SS) watermarking has proven to be efficient, robust and cryptographically secure. Each bit of watermark information is embedded over wide spectrum of the host signal based on spectrum spreading concept of SS modulation in digital communication and can easily be integrated with many existing data transmission scheme. This has made SS watermarking method more attractive during re...

Klasifikasi Data Cardiotocography Dengan Integrasi Metode Neural Network Dan Particle Swarm Optimization

Backpropagation (BP) adalah sebuah metode yang digunakan dalam training Neural Network (NN) untuk menentukan parameter bobot yang sesuai. Proses penentuan parameter bobot dengan menggunakan metode backpropagation sangat dipengaruhi oleh pemilihan nilai learning rate (LR)-nya. Penggunaan nilai learning rate yang kurang optimal berdampak pada waktu komputasi yang lama atau akurasi klasifikasi yan...
