CHOICE OF PRIMARY CODING ALGORITHM FOR CELLULAR SYSTEMS

. This article discusses the development of an adaptive primary codec for satellite communication systems, focused on minimizing delay and efficiently utilizing the communication channel. Special attention is given to the analysis of the CELP, MELP, and Codec2 standards, their characteristics, applications, and potential adaptations for satellite communication conditions. The advantages and disadvantages of each standard are examined, as well as their potential to ensure high resilience to interference, packet loss, and achieving the required speech quality characteristics at low bitrates.
