Signalling and the broadband Internet

IEE Colloquium on Signalling for Broadband, 1995
This paper is written from the perspective of an applications developer rather than a network operator or switch manufacturer. The main focus is on the needs of domestic users, and the companies that want to provide broadband services to them. It looks at the development of broadband applications in the real world. Then the application of those lessons

Broadband virtual private network signalling

BT Technology Journal, 1998
In the corporate voice networks, the virtual private network (VPN) configuration is particularly useful where a shared network infrastructure can be more cost effective and flexible than dedicated leased lines. Current standards for VPN use the international narrowband private signalling system QSIG.

DOA estimation for broadband chirp signals

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
We derive two new methods, based on the ambiguity function, for estimating the direction-of-arrival (DOA) of broadband chirp signals. These new methods make use of the time-frequency structure of the chirp signal and can be applied to any aperture array and any chirp rate. As long as the signals are separable in the ambiguity function plane, the number

Detection of broadband signals in signal-dependent noise

The Journal of the Acoustical Society of America, 1990
The optimum choice of detection nonlinearities for generalized radiometric detection of broadband random signals in noise is considered for the situation in which the signals and noise are individually and mutually dependent random sequences. Explicit solutions to integral equations specifying the optimum nonlinearities are derived, and an analysis of ...

Effective Bandwidths of Broadband Chaotic Signals

IEEE Journal of Quantum Electronics, 2012
We propose and study a new definition for the effective bandwidths of the broadband chaotic signals, which sums up only those discrete spectral segments of the chaos power spectrum accounting for 80% of the total power. Compared to the definitions used conventionally, which tend to overestimate the effective bandwidths of the chaotic signals, the ...

ITU-T's internodal broadband signalling protocol

BT Technology Journal, 1998
Broadband integrated services user part (B-ISUP) is an internodal signalling protocol defined by the International Telecommunications Union (ITU-T). Its purpose is to establish, maintain and release asynchronous transfer mode (ATM) connections in a public network, via the use of signalling messages.

Signaling networks in broadband-ISDN environments

Conference Proceedings of the 2000 IEEE International Performance, Computing, and Communications Conference (Cat. No.00CH37086), 2002
The analysis of common channel signaling under broadband environments such as ATM is needed to characterize the performance of various SS7 signaling network topologies. The paper presents an analysis of Broadband-ISDN signaling network architectures in an ATM environment.

Signalling on the broadband subscriber access

IEEE Global Telecommunications Conference, 1989, and Exhibition. 'Communications Technology for the 1990s and Beyond, 2003
The access signaling infrastructure for a B-ISDN (broadband integrated services digital network) which is based on asynchronous transfer mode (ATM) is considered. A current proposal involves replacing the common signaling-channel approach, as in a narrowband ISDN, by separate dedicated signaling channels per terminal on the subscriber access line in a ...

BROADBAND SIGNAL SIMULATION IN SHALLOW WATER

Journal of Computational Acoustics, 2003
Today's minimum requirements for ocean acoustic models are to be able to simulate broadband signal transmissions in 2D varying environments with an acceptable computational effort. Standard approaches comprise ray, normal mode and parabolic equation techniques.

Pervasive broadband: opportunities for signal processing

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003
Summary form only given. With the emergence of broadband telecommunications, we are moving in well-measured steps from nearly universal telephony to increasingly pervasive multimedia services. The author describes some of the fundamental opportunities that this context presents to the practitioners of advanced signal processing.
