Since faults are inevitable, quick detection, identification, and recovery are crucial to make the systems more robust and their operation more reliable. This paper proposes a novel event correlation scheme for fault identification in communications network. This scheme is based on the algebraic operations of sets. The causality graph model is used to describe the cause-and-effect relationships between network events. For each problem, and each symptom, a unique prime number is assigned. The use of the greatest common devisor (GCD) makes the correlation process simple and fast. A simulation model is developed to verify the effectiveness and efficiency of the proposed scheme. From simulation results, we notice that this scheme not only identifies multiple problems at one time but also is insensitive to noise alarms. The time complexity of the correlation process is close to a function of n, where n is the number of observed symptoms, with order O(n/sup 2/); therefore, the on-line fault identification is easy to achieve.","PeriodicalId":414137,"journal":{"name":"IEEE GLOBECOM 1998 (Cat.

In the reverse link non-coherent detection is applied without pilot signals. In this paper, the reverse link pilot-tones aided synchronization which utilizes the aided pilots to facilitate the timing and carrier recovery (with linear complexity to the number of users) is proposed based on the development of multiuser synchronization. In the meanwhile, with proper separation of these transmitted aided pilot tones over frequency and/or time domain controlled by the base station, it is easy to identify these pilots. With more practical considerations, the proposed pilot-tones aided synchronization still works when the other mobile handsets transmit their packets simultaneously. The enhanced-performance linear minimum mean square error detector which considers the aided pilots and outperforms the linear minimum mean square error detector is proposed and analytically shown to provide better performance. In the simulations, the huge performance gain clearly illustrates potential applications in future CDMA wireless systems.","PeriodicalId":414137,"journal":{"name":"IEEE GLOBECOM 1998 (Cat.
