Customer requirements are becoming more exacting as quality expectations rise and the demand for new services escalates. With the increasing range of services, bandwidth requirements are also increasing. Although 64 kbit/s circuits are adequate for telephony, the emergence of multi-media services is spawning massive increases in bandwidth requirements.

Generating broadband random Gaussian signals
Technical Physics Letters, 2010General approaches to the problem of generating random Gaussian signals are considered, a variant of practical implementation of such a generator is proposed, some technological aspects of the formation of active device structures are discussed, and spectral characteristics of the output noise signal are presented.

Signalling protocol for broadband ISDN
[Conference Record] SUPERCOMM/ICC '92 Discovering a New World of Communications, 2003The authors focus on a signaling protocol for the long-term broadband ISDN (B-ISDN), for which work is being done by CCITT SGs XVIII and XI. A brief description of services handling which must be performed by a broadband network is given. The advantages of the call control and bearer control functional separation, needed to support the complex services

Broadband UNI Signaling Techniques
1994This paper evaluates the possibility of extending the Release 1 Broadband Integrated Services Digital Network (BISDN) User-Network Interface (UNI) signaling protocol, called Q.93B, to support services in a Release 2 BISDN. Two Q.93B-based protocols are considered: a monolithic protocol and separated protocol.

Advanced optical signal processing of broadband parallel data signals
2016 IEEE Photonics Conference (IPC), 2016Optical signal processing may aid in reducing the number of active components in communication systems with many parallel channels, by e.g. using telescopic time lens arrangements to perform format conversion and allow for WDM regeneration.

Bearing resolution limits for broadband signals
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003Analytical lower bounds on bearing accuracy for two broadband radiating sources which are located within a beamwidth at an array are presented. The power levels of the radiated signals are not necessarily known a priori. It is demonstrated that at modest signal-to-noise ratio, accuracy reductions in a multiple-source setting depend on the inverse ...

Statistical signal processing in broadband reflectometry
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002Microwave broadband reflectometry is used to determine the spatial distribution of plasma density (density profile) in experimental nuclear fusion devices. The position of each plasma reflecting layer is evaluated by Abel integration of the phase rate of the reflectometric signal that results from mixing the plasma incident and reflected waves.

Signal processing for broadband communications
European Transactions on Telecommunications, 1992AbstractSignal processing affects all aspects of broadband communications: terminals, transmission media and networking techniques. In this context, the paper provides a review of several basic signal processing concepts, which can now be implemented and exploited, with the present technological capabilities: perfect filter banks, fast adaptive ...

The development of broadband signalling platforms
BT Technology Journal, 1998Mao Zedong once said: "All genuine knowledge originates in direct experience." This paper describes the experiences gained through a range of development projects, all concerned with the design, development, demonstration and maintenance of real broadband signalling systems.

Ideal amplification of broadband signals
International Journal of Microwave and Wireless Technologies, 2013This paper describes a digital signal processing (DSP) method for achieving “ideal” amplification, maximizing both the average output signal power and power-added-efficiency for any signal waveform and any power amplifier (PA) transfer characteristic. Detailed algorithms are described for optimally accomplishing peak reduction (PR), predistortion (PD ...
