Abstract  Abstract

The present invention relates to a method for noise suppression in a telecommunication system, in which telecommunication system is framed by transmitting noisy ducts, determining the amount of noise of the ducts by determining Based on the determined value of the total channel energy (Ech) measured during the transmission of the information frame, we determine the spectral channel energy pre-slip (EdB), the value of the channel energy measured during the transmission of the current information frame (Ech). Determine the spectral energy difference (DE) between the currently transmitted and the previous number of information frames and the spectral energy difference (DE) by determining the spectral energy difference (DE) between the currently transmitted and the previous number of information frames. In the knowledge of the total channel energy (HUF), the estimated noise value of the channel is further corrected. for speech coding, in which speech is arranged in an information frame in a telecommunication system, it is transmitted in noise channels, which speech coder (100) makes noise in the instantaneous speech sample frame between the instantaneous speech sample frame difference channel energy (Ech) and spectral channel energy average (EdB) (DE) has a system of noise, noise and noise (109) and has a coding (102) of the speech sample with low noise.Å•
