COMPERATIVE ANALYSIS OF VOICE CODECS FOR LTE COMMUNICATION NETWORKS

4G mobile connectivity protocol, LTE (Long Term Evolution), is lower dormancy and higher data rates. LTE overseers may utilize the current circuit to control voice through the fallback procedure Networks exchanged as LTE is totally Internet Protocol (IP) advancement. Voice over IP administrations (VoIP) are needed to give the voice over IP associations, similar to the Internet, to prevent this. Voice Codec is one of the basic sections of VoIP that can be communicated on Internet and change simple signs into compacted computerized parcels. In any case, there are various sorts of codecs that lift voice streams dependent on transfer speed and application necessities. There is, still, no default codec reasonable to everybody. Some codecs have better effectiveness, with different conditions and therefore the transmission capacity is lower. Every one of these qualities will influence the Ultimate corporate assortment of codecs. In this paper, investigation on various kinds of codecs is held that can be utilized with ns-3 test system in VoIP over LTE. Moreover, we have proposed some framework for examination of VoIP traffic over LTE nature of administration (QOS) by arranging various VoIP codecs. Furthermore, as far as deferral, jitter, parcel misfortune and error-proposed scenarios, the study of the different VoIP codecs across the LTE network has been evaluated
