Although the traditional task of communication protocols is the transmission of data, this is actually not completely sufficient if it is used in safety sectors. Therefore, it must be enhanced. In order to detect and overcome failures in systems, risk analysis and failure measurement must be taken into account in each safety-related system. This paper(More)
In this paper, by using a new envelope estimation algorithm and a geometrical adaptive threshold method; we present a novel method to improve the performance of ITU-T G.729.B systems in various noisy environments. The proposed system has minimum change from this standard. We compare the performance of the proposed method with G.729B, ETSI AMR option 1 and 2(More)
