Performance Analysis for VoIP System using Finite Impulse Response Algorithm in Noisy Environment

H.P. Singh, S. Singh and J. Singh

The speech signal is degraded due to delay, jitter and packet losses, when passed through different network layers of internet protocol based Voice over Internet Protocol (VoIP) system. The speech quality of the VoIP system can be improved by reducing the background noise, codec distortions and various network impairments such as packet loss, delay and jitter. The work in this paper proposes the Finite Impulse Response filter (FIR) based scheme for speech quality improvement of the VoIP signal. The lab experiment is performed to realize the VoIP system and to obtain the degraded database. For various noisy conditions, the performance of the enhanced VoIP signal is evaluated using Perceptual Evaluation of Speech Quality (PESQ) measurement for narrowband signal. The results show much improvement in speech quality with proposed method.
