However, in the traditional network management strategies, the signallings are recorded first, and then analyzed later. This will cause serious and disastrous problems in the high-speed real-time networks like ATM. How to reliably analyze in real time the signalling status and quickly react is becoming an important issue in ATM networks. Therefore, in this paper, a connectionist system, based on neural network and expert system technologies, is designed for analyzing the signalling in ATM networks. The proposed system is divided into two modules: detection and diagnosis. The former module is responsible for detecting whether the information element of network signalling is normal or not and is built by a counter propagation neural network. When the detection module finds out the abnormal status, the diagnosis module is driven to infer the detailed reasons by counter propagation neural network and the expert system will execute the corresponding diagnostic actions. The developed system will be realized by VLSI technology and embedded in the control plane of broadband integrated services digital networks (B-ISDN). It's our belief that the designed chipset is a topnotch component for real-time error recovery in ATM networks.","PeriodicalId":323626,"journal":{"name":"1994 IEEE GLOBECOM.

However, these techniques often assume knowledge of system parameters, suck as signature waveforms for all users, and associated timing, which may not be available, or may be inconvenient to obtain in practice. Recently proposed adaptive minimum mean squared error (MMSE) detectors do not require knowledge of signature waveforms; however, these techniques require a training sequence for adaptation. Here we propose a blind multiuser linear detector which requires only knowledge of the desired user's signature sequence (and associated timing). In particular, it does not require the use of a training sequence. Our approach is to decompose the filter impulse response into the sum of two orthogonal components: the matched filter corresponding to the desired user plus an adaptive filter. We show that if the adaptive filter is chosen to minimize the energy (i.e., variance) of output samples at each symbol interval, then a scaled version of the MMSE detector is obtained. Based on this observation, a simple adaptive gradient algorithm is derived, and numerical examples are presented which illustrate its performance in a synchronous CDMA system.","PeriodicalId":323626,"journal":{"name":"1994 IEEE GLOBECOM.

BDCA systems make interference measurements at both radio ports and handsets of potential operating channels prior to channel selection, and channel selection is based on the joint measurements. Independent uplink and downlink power control is used to minimize interference. By using BDCA for indoor wireless operation, high capacity and high quality 32 kbps voice circuits can be provided with only two 5 MHz segments of spectrum. If nearby public access systems use adjacent spectrum segments and not the same spectrum segments, the potential interference problems of adjacent radio systems with very different radio port coverage-area sizes can be avoided, but handsets can readily access both types of systems. The performance of an efficient BDCA scheme suitable for indoor wireless operation which is highly compatible with WACS is described in this paper.","PeriodicalId":323626,"journal":{"name":"1994 IEEE GLOBECOM.
