Signalling protocol for broadband ISDN

[Conference Record] SUPERCOMM/ICC '92 Discovering a New World of Communications, 2003
The 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

Optoelectronic broadband signal processor

OSA Annual Meeting, 1993
Because of its low loss (<0.2 dB/km) and low dispersion (<17ps/nm/km), optical fiber has been widely recognized for its potential in delay line signal processing applications [3, 4, 5]. However, the high insertion loss of optical switches and the high cost of optical amplifiers restrict the implementation of a reconfigurable optical fiber delay ...

Section processing of broadband signal

2010 The 2nd Conference on Environmental Science and Information Application Technology, 2010
The purpose of this paper is to segment wide signal. The methods and advantages of the method employed (1) In band-pass filter, used multi-rate during the signal sampling to reduce computation and storage. (2) Used Filter Banks process wide frequency signal, to overcome the drawbacks and deficiencies that large volume calculation bring about when using

The development of broadband signalling platforms

BT Technology Journal, 1998
Mao 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.

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 detection of signals with unknown spectra

ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
The problem of detection of a broadband wide sense stationary Gaussian signal of unknown power spectral density in white Gaussian noise is addressed. By modeling the signal in noise as an autoregressive process a generalized likelihood ratio test is formulated for the parameters of the autoregressive process.

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.

Detection of broadband dispersive signals

IEEE International Conference on Systems Engineering, 1989
Several methods are developed for detection of signals with known frequency characteristics, such as detection of chirp radar signals using matched filters. An innovative method of detecting broadband dispersive signals is proposed where the known characteristics of exponential frequency decay form the basis of detection.

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 ...

Broadband UNI Signaling Techniques

1994
This 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.
