Distributed event monitoring is an important service for fault, performance and security management. Next generation event monitoring services are higly distributed and invovling a large number of monitoring agents. In order to support scalabel event monitoring, the monitoring agents use IP multicasting as a group communication for exchanging events and control information. However, dueto the d...

A controlled subjective test was carried out to assess selected spatial qualities of three virtual home theatre processors. The subjective results were used to evaluate a number of objective measurements based on the interaural cross-correlation coefficient (IACC). A novel implementation of the IACC was found which appears to correlate well with the subjective data.

According to the advantages of chaotic analog sequences and chaotic binary sequences, this paper proposes a method generating chaotic binary spread-spectrum sequence by multilevel quantifying. This paper proved that even correlation and odd correlation between such sequences of length N are all Gaussian distributed with mean 0 and variance N, the even of mean-square cross-correlation is N, and ...
