OFDM Spread Spectrum Communications

1998
Orthogonal frequency division-multiplexing (OFDM) [1, 2] has received considerable attention as a method to efficiently utilize channels with non-flat frequency responses and/or non-white noise. In its most common form, a high rate data stream is divided up among the many carriers in the system in a manner which optimizes the capacity of the overall ...

Interference to digital broadband communications and spread spectrum communications

2012 IEEE International Conference on Consumer Electronics (ICCE), 2012
Interference from DTV signals to cellular 700 MHz wireless phones may limit their acceptance by the public. Such interference has been reported to the FCC. The interference mechanism involved is 3rd order non-linearity of the analog front end of cellular phones. Interference to GPS signal reception has been documented by a Technical Working Group.

Consumer Communications Based on Spread Spectrum Techniques

Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94), 1995
This paper shows consumer applications of spread spectrum techniques in the following areas: power line communication, data carrier, radio remote control, ISM wireless LAN, vehicle to vehicle communication, and digital TV broadcasting. One of the most difficult problems for a spread spectrum communication system is how to synchronize the receiver to ...

Spread Spectrum Techniques for Mobile Communications

2004
Wireless mobile communications has greatly benefited from the adoption of advanced signal processing techniques and components. In particular, the advent of low-cost very large scale integrated (VLSI) chips has allowed the design and implementation of efficient communications systems based on spread-spectrum signals, namely, the different code-division

Interference rejection techniques in spread spectrum communications

Proceedings of the IEEE, 1988
It is argued that the ability of a spread-spectrum system to withstand interference, both intentional and unintentional, is probably its greatest asset. Any spread spectrum receiver can only suppress a given amount of interference; if the level of interference becomes too great, the system will not function properly.

Spread Spectrum Communication Satellite

2022
The need for high returns on investments becomes increasingly necessary in the current environment of shrinking defense budgets. The Naval Postgraduate School’s Petite Amateur Navy Satellite (PANSAT) endeavors to demonstrate the application of technology for digital communication while also fulfilling the long-term needs of space education for military

Introduction to spread spectrum communications

1985
This book offers an introduction to the methods and concepts applied in modern communications, and suggests areas for future development and refinement. The term spread spectrum is used to describe a class of modulation techniques in which the data stream is coded in such a way that the total information rate is higher than the data rate. However, this

The evolution of spread-spectrum multiple-access communications

Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94), 1995
This paper contains a brief history of electrical communications, emphasizing the emergence of multiple-access and spread-spectrum techniques. Events that led to the commercialization of spread-spectrum signalling are described. >
