From an investigation of a statistical model-based voice activity detection (VAD), it is discovered that a simple heuristic way like a geometric mean has been adopted for a decision rule based on the likelihood ratio (LR) test. For a successful VAD operation, the authors first review the behaviour mechanism of support vector machine (SVM) and then propose a(More)
The IP multimedia subsystem (IMS) could very well be the best solution for most telecom operators. The more recent releases have included interfaces to fixed line networks and wireless LANs. This has consequences both for the migration of the core network as well as the integration of future mobile services and applications. Also, an interworking between(More)
The Long Term Evolution supports high peak data rates (100 Mb/s in the downlink and 50 Mb/s in the uplink), low latency (10ms round-trip delay) in different bandwidths ranging from 1. 4MHz up to 20MHz. In mobile broadband networks like LTE, the high performance of the radio network can be realized with proper scheduling of resources for different types of(More)
