Improved Voice Quality of GSM Network through Voice Enhancement Device
نویسندگان
چکیده
Voice quality assessment is an emergent aspect in Global System for Mobile Communications (GSM) network. The evolution of GSM also able in principle to take benefit from end to end services.GSM network inherently include elements such as noisy intermediate equipments that degrade the quality of transmitted voice signal.GSM network presents an alternate method to improve quality and customer experience based on International Telecommunication Union (ITU)-TG107. This research paper provide overview of voice quality in GSM network by presenting the methods for voice quality enhancement, functionality of Voice Enhancement Device(VED).Results from experiments based on voice quality measurements perform on various wireless network with advance VEDs deployed are presented and discussed. Comparison of the results objective measurements of ITU-TG107 based quality with the result of lab listening test. This shows the voice quality improvement achieved by deploying VED in typical network condition. Keywords— Voice Quality, GSM, VED, ITU-TG107, PESQ

Implementation and Performance Analysis of Reliable and Secure End to End Voice Encryption over Public Mobile Network Based on Frequency Domain Using Dual Processor in FPGA Platform
This research aims in designing a method for implementing end-to-end voice encryption over mobile network such as GSM that independent to phone devices, operating system and network devices. The proposing method is an encryption system in domain frequency to keep the encryption signal remain within the range of sound frequencies that can be transmitted through GSM/2G/3G. This method differ comp...
متن کاملTraffic Analysis in GSM/GPRS Networks using Voice Pre- Emption Priority
-In this paper the performance of radio resource allocation in GSM/GPRS network is analyzed. A two dimension Markov chain is presented using guard channels for handover calls. Also priority is given on reservation of QoS of voice service by applying priority for voice calls to pre-empt GPRS data packets. Key-Words: GSM, GPRS, Networks.
متن کاملEffect of Functional Endoscopic Sinus Surgery on the Voice Quality among Patients with Rhinosinus Polyposis
Introduction: Rhinosinus polyposis is associated with voice quality reduction. There has been little evidence about the efficacy of rhinosinus polyps surgery on patients' voice quality so far. The aim of the present study was to evaluate the nasality and acoustic voice changes after rhinosinus polyposis surgery. Materials and Methods: The population in this study compo...
متن کاملPerformance Evaluation of Data Subsystem in GSM/GPRS Using Complete Sharing of Bandwidth
In this paper we evaluate the performance of data users in a GSM/GPRS system using queuing analysis and the QDB approach. GPRS has been introduced in GSM as a proposed data packet service over the air interface. Currently GPRS uses a fixed number of time slots, which are not shared with GSM voice users. Therefore the QoS of GSM users that are circuit switched is decreased. Here we propose a com...
متن کاملCapacity analysis of voice over IP over GERAN with statistical multiplexing
The requirements in terms of service flexibility, spectrum efficiency and speech quality introduce new challenges when voice is transmitted over packet and over wireless. This paper analyses the perceived voice quality when voice frames are transported on packet radio bearers of GSM/EDGE Radio Access Networks (GERAN) and are statistically multiplexed. The resulting quality depends on the link l...
