Physical component performance degradation detection based on error probability analysis

The detection and diagnosis of physical layer faults at system level in communications systems remains problematic. This paper presents a cross layer fault detection scheme, suitable for implementation at higher levels in a communications system,with the ability to detect and diagnose the cause of physical layer failure which results in impaired performance. It is based on the distribution of symbol error frequency and the probability of error of the underlying modulation scheme used in the communications system. With this knowledge, a simple counting algorithm is proposed as a diagnostic tool to implement the methodology

A Fault Diagnosis Mechanism for a Proactive Maintenance Scheme for Wireless Systems

This paper presents the fault diagnosis mechanism for a proactive maintenance scheme for wireless systems which is aimed at reducing the high operational costs encountered in the wireless industry by decreasing maintenance costs and system downtime. An on-line monitoring system, based on the aforementioned fault diagnosis mechanism, is used to identify performance degradation, as well as its possible sources, so as to ensure that maintenance occurs only when necessary
