Digital signaling for radio paging
IEEE Transactions on Vehicular Technology, 1981Some of the factors affecting the design of a binary signaling format for high capacity wide area digital radio paging are discussed. Topics considered are synchronization, battery economy techniques, error control coding to ensure acceptable success and false call rates, and the choice of bit rate.

A 60-GHz 38-pJ/bit 3.5-Gb/s 90-nm CMOS OOK Digital Radio
IEEE transactions on microwave theory and techniques, 2010A 60-GHz fully integrated bits-in bits-out on-off keying (OOK) digital radio has been designed in a standard 90-nm CMOS process technology. The transmitter provides 2 dBm of output power at a 3.5-Gb/s data rate while consuming 156 mW of dc power ...

The Radio and/as Digital Productivism
2019Early theorists of the radio understood the medium's potential to radically transform both the technological apparatus and its use-value as a generator of identities and attitudes. Bertolt Brecht famously demanded that the radio's communication be two- rather than one-sided, while Boris Arvatov hailed radio as a »socialist object,« defined by its ...

Digital Telecommunications Radio Systems
MTT-S International Microwave Symposium Digest, 2005The increasing need for digital transmission facilities has generated requirements for microwave digital transmission systems that are reliable, have high performance and are spectrally efficient. Application considerations, including interference, frequency planning and growth, of such a system are discussed.

[Proceedings] WESCANEX '91, 2002
An eight-channel VHF digital radio is described. The radio was designed to provide service to remote communities located 100 km or more from the nearest node of a microwave LOS (line-of-sight) network. Some of the novel design features of the radio are briefly discussed. The performance results of a field trial in northern Saskatchewan are presented. >

Digital radio frequency memory
Electronics & Communications Engineering Journal, 1990Digital radio frequency memory (DRFM) is a technique in which high-speed sampling and digital memory is used to store radio frequency and microwave signals. It is becoming a popular technique for the implementation of false-target ECM systems. The paper discusses the principles of DRFM and the advantages of alternative system architectures.

Programmable channelized digital radio
[Proceedings] NTC-92: National Telesystems Conference, 2003Ongoing work by GEC-Marconi Electronic Systems Division in the development of a multifunction, common module, programmable digital radio/modem is described. The radio system handles conventional narrowband and spread-spectrum waveforms. The architecture developed is a programmable channelized approach.

Digital Radio for Mobile Applications
AT&T Technical Journal, 1993The technology of time-division multiple-access (TDMA) and code-division multiple-access (CDMA) promises to significantly improve the capacity and operation of existing analog cellular networks. AT&T has been on the leading edge of these breakthroughs, developing trial and commercial systems for both of these advanced digital radio technologies.

Digital Microwave Radio Program
MILCOM 1982 - IEEE Military Communications Conference - Progress in Spread Spectrum Communications, 1982In 1981 CECOM placed four contracts for the exploratory development of ECCM techniques which are to be considered for use in a new digital microwave radio development. A spread spectrum modem is under development which will operate in the 4.4 to 5.0 GHz band. The modem will also be designed to operate, with minor changes, in the 14.4 to 15.35 GHz range.
