Abstrucz-This monograph reviews events, circa 1920-1960, leading to the development of spread-spectrum communication systems. The WHYN, Hush-Up, BLADES, F9C-A/Rake, CODORAC, and ARC-SO systems are featured, along with a description of the prior art in secure communications, and introductions to other early spreadspectrum communication efforts. References to he available literature from this period are included. 

Multi-User Communication using Chaotic Frequency Modulation

This paper considers the use of the chaotic frequency modulation (CFM) in multi-user communica- tions and evaluates the BER performance of CFM.

An Introduction to Spread Spectrum Systems

This report is a tutorial introduction to spread spectrum communication systems, and it should be accessible for a reader who has basic knowledge of digital modulation and channel coding. The

ESTIMATION OF THE SPREADING WAVEFORM OF A SPREAD SPECTRUM TRANSMISSION

This paper proposes a method for estimating the spreading waveform without prior knowledge on the transmitter, based on eigenanalysis techniques, and shows that the spreading sequence can be recovered from the first and the second eigenvectors.

Subnoise Signal Detection and Communication

By eliminating high-speed electronics from the receiver, it is now possible to access the entire radio-frequency range that extends beyond 100 GHz, and it is anticipated that new, band-unrestricted wireless services will emerge to maximize throughput, mitigate interference, and achieve a high level of physical security.

On cracking direct-sequence spread-spectrum systems

The proposed identification method is based on maximizing the spectral norm of a sample covariance matrix, which achieves smaller estimation error than the existing method of maximizing the Frobenius norm.

THE CASE FOR SPREAD-SPECTRUM SIGNALING IN INTERSTELLAR MESSAGING

It is demonstrated that a transmitted interstellar beacon signal can be chosen in such a way that it is intrinsically immune to interference.

Intersect embedding on OFDM channel — A stego perspective

This paper proposes a technique to increase the efficiency of OFDM by incorporating embedding in it, where the data is embedded in the system following the steps of modulation and cyclic prefix in the OFDM process.

Interstellar Communication: The Case for Spread Spectrum

Direct Sequence Spread Spectrum

After examining the fundamental concepts of spread spectrum, direct sequence is discussed in detail, along with various pseudo-noise methodologies, concluding with several examples of commercial applications.

ON THE PERFORMANCE ENHANCEMENT OF SELF ENCODED SPREAD SPECTRUM IN WIRELESS COMMUNICATION

The performance evaluation of SESS with chaotic initial sequence in different channel conditions such as Additive White Gaussian Noise channel and Rayleigh fading channel is presented to ensure its applicability as a secure communication system.

Two radio propagation channels for beyond-the-horizon communications, troposcatter, and HF are currently being reexamined with renewed interest in the use of high frequency (HF) and Troposcatter communications for networks carrying digital traffic.

Radio signalling system for remote control

In a radio signalling system, signals from receiver antennae coils L1, L2, L3, which may be orientated along mutually orthogonal axes, are fed via filters F, amplifiers A, and absolute magnitude

Theoretical Diversity Improvement in Frequency-Shift Keying

Methods of using diversity to improve frequencyshift keyed receptions in the presence of Rayleigh fading are analyzed. In the absence of prior information about signal amplitude and phase, square-law

An Error-Correcting Encoder and Decoder of High Efficiency

A group effort has demonstrated the applicability of regenerative shift register sequences to error-correcting codes and shown that the interrelationships between the bits of these binary sequences can be used to design a decoder of extreme simplicity.

An Analysis of the Phase Coherent - Incoherent Output of the Bandpass Limiter

Many applications of the bandpass limiter (BPL) involve coherent demodulation following the limiter. It is shown that as a result of demodulation, the signal mean and the noise variance are direct

Design and performance of phase-lock circuits capable of near-optimum performance over a wide range of input signal and noise levels

This paper explains how minimum-rms-error loops may be designed if the input-signal level, input-noise level, and a specification for transient performance are given.
