This work aims to obtain a signal processing method to neutralize the mechanical vibration sound from the electrolarynx which is used as a supporting device for speech restoration of people who have gone under resection operation over their larynxs due to various reasons. After the main problem of electrolarynx which is a noninvasive solution to the speech production problem arised due to the resection...
The usage of Internet Protocol TV (IPTV) deployments in the consumer electronics market is growing very popularly in recent years. In IPTV systems, Quality of Experience (QoE) is very critical factor for end-user satisfaction. Existing and future IPTV systems will offer a large number of channels to users. The most important factors that affects to QoE in IPTV systems are channel zapping and channel...
To utilize the total resources in cellular/WLAN integration for both cellular and WLAN network, their different channel allocation strategies should be considered and efficient resource management techniques are required. In this paper, we proposed a new call admission scheme to utilize the coupled resources effectively. Proposed scheme, by taking the different resource sharing strategies of both...
In integrated voice/data cellular mobile networks, the most important consideration is to utilize the resources in an efficient way and maintain the required quality of service (QoS). In this paper, we proposed a new call admission control scheme for improving efficiency of resource utilization. Proposed scheme restricts the new and handoff voice and data calls arrived to system by finding the optimal...
To efficiently utilize the total resources and to serve mobile users demanding for different types of service, system resource utilization of these services should be considered, and efficient resource management techniques should be developed. In this paper, we propose a new call admission control (CAC) scheme jointly with resource management by considering the two service types: prioritized calls...
In this work, speech signals are modeled by means of the so-called pre-defined “signature functions”. The pre-defined signature functions are generated using the statistical properties of the speech signals. It has been exhibited that, with a few basic signature functions, any speech signal can be generated within a tolerable error.
