Abstract
Poor voice quality in VoIP models during communication has been a common occurrence which VoIP users experience, this can be frustrating when users cannot communicate efficiently. Most people find it difficult to think straight when they make calls and there is an echo. In addition to this frustration, the caller’s money, time, effort, energy is all wasted without compensation of any kind. Users are also frustrated by not receiving, transmitting or misunderstanding voice messages correctly. Given the need for voice quality in calls, it is of no importance when there is no proper communication. This study aims to reduce the threat of bad calls and improve the quality of voice calls. Nonetheless, we need to raise the filter duration to a high value in some real telecom’s environments with long echo delays. But, because of high computational complexity, it is not efficient in efficiency. In this study, we suggest a solution that uses a computational formula to compensate long echo, delay, packet loss, jitter and noise. The model designed was developed using MATLAB 2019b. This approach demonstrated productivity in terms of both voice quality and system speed.
Highlights
VoIP was one of the ways in which the cost of calling over long distances was reduced, for international calls
Call quality is affected by challenges like echo, jitter, noise, packet loss and delay[1]
Quality of hearing is related to quality of sound, conversational quality refers to both conversation and listening qualities which may include echo or delay issues that can affect conversation, whereas, transmission qualities include network connection that is used to transmit the voice, Revised Manuscript Received on May 05, 2020. * Correspondence Author Amanze, Ruth C*., Department, School of Computing and Engineering
Summary
VoIP was one of the ways in which the cost of calling over long distances was reduced, for international calls. Quality of hearing is related to quality of sound, conversational quality refers to both conversation and listening qualities which may include echo or delay issues that can affect conversation, whereas, transmission qualities include network connection that is used to transmit the voice, Revised Manuscript Received on May 05, 2020. II.REVIEW OF RELATED WORKS [4] reviewed various scholarly articles to have a comprehensive and concise report on VoIP Their opinions include the conceptualization of the Generation (NGN), a packet-based network capable of delivering telecommunication services, VoIP may make use of existing structures. It was found that the controlled test and field test showed a marked difference in Downlink (DL) Path loss greater than 130dBIn field testing, the locking function of physical cell identity (PCI) was used but this was not recorded during controlled test, which equals data collection was not very optimized for the study
