Efficient digital filter banking algorithm for wireless VoIP

Abstract

Due to advancement in Today’s information and communication technology, Voice over IP (VoIP), emerged as one of the most reliable and cost efficient technology over the traditional ones, the same used to transmit the voice data over available computer networks using standardized protocols such as Internet Protocol (IP). Along with the advantages such as scalability and security, VoIP has some threats to deal with such as voice quality and interference. In this research article, an efficient digital filter banking scheme is proposed and the same is implemented after decoding the signal into the system as post-processor. To analysis the performance of the proposed, it is evaluated under various network conditions. Later, the proposed scheme is compared with the traditional one. The proposed scheme shows better results in terms of speech quality with the rational ones.
