Chaotic iterations versus Spread-spectrum: topological-security and stego-security

A new framework for information hiding security, called topological-security, has been proposed in a previous study. It is based on the evaluation of unpredictability of the scheme, whereas existing notions of security, as stego-security, are more linked to information leaks. It has been proven that spread-spectrum techniques, a well-known stego-secure scheme, are topologically-secure too. In t...

An Interpolated Frequency-Hopping Spread-Spectrum Transceiver

A technique of spread-spectrum transmission, interpolated frequency-hopping (IFH), is presented. IFH employs a carrier that moves smoothly and continuously in frequency, helping to alleviate problems, such as spectral splatter and transient mismatch, which are a concern in conventional phase-locked loop (PLL)-based frequency-hopping spread-spectrum systems. In IFH, the pseudorandom hopping code...

Analysis and design of a frequency-hopped spread-spectrum transceiver for wireless personal communications

Personal Communications Services (PCS) require low-power radio technologies. One such transceiver architecture employing frequency-hopped spread-spectrum techniques is presented. System features such as antenna diversity with equal-gain combining and sequential hop combining are incorporated into the transceiver design to achieve robust wireless digital data transmission over fading channels. A...

Fixing, padding and Embedding – A Modulated Stego

Broadband application of wireless communication calls for good signal to noise ratio (SNR) and variable high data rates. In the midst of a spate of available techniques, Orthogonal Frequency Division Multiplexing (OFDM) has proven to be effective. OFDM systems have high tolerance towards multipath effects in fading channels. Wireless communication will become tortuous in the presence of Inter S...

FPGA-Based Implementation of a Hybrid DS/FFH Spread-Spectrum Transceiver

In recent years there has been great interest in using hybrid spread-spectrum (HSS) techniques for commercial applications, particularly in the Smart Grid, in addition to their inherent uses in military communications. This is because HSS can accommodate high data rates with high link integrity, even in the presence of significant multipath effects and interfering signals. A highly useful form ...
