Comparative analysis between chaotic sequence and PN sequence in spread spectrum system

open access: yesJournal of Measurement Science and Instrumentation, 2016
This paper introduces two kinds of sequences used in spread spectrum communication system:pseudo-noise(PN)sequence generated by linear feedback shift register(LFSR),such as m-sequence and Gold sequence,and the chaotic sequence generated by the ...

Adaptive Watermarking Scheme Using Biased Shift of Quantization Index

open access: yesJournal of Electrical and Computer Engineering, 2010
We propose a watermark embedding and extracting method for blind watermarking. It uses the characteristics of a scalar quantizer to comply with the recommendation in JPEG, MPEG series, or JPEG2000.

Implementation of Pass Transistor Logic and C2MOS Linear Feedback Shift Register (LFSR) Circuit using FPGA and PSpice

open access: yesInternational Journal of Electrical and Electronics Research
In this paper, a 4-bit Linear Feedback Shift Register (LFSR) is implemented based on a well-designed architecture combining using Pass-Transistor (PT) and Clock Complementary Metal Oxide Semiconductor (C2MOS) logic techniques. The D-flip flop registers and the XOR gates are the main parts of the propose LFSR.

A Search for Good Pseudo-random Number Generators : Survey and Empirical Studies

open access: yes, 2018
In today's world, several applications demand numbers which appear random but are generated by a background algorithm; that is, pseudo-random numbers. Since late $19^{th}$ century, researchers have been working on pseudo-random number generators (PRNGs).
