Abstract: According to increase of social and economical activity, the mobile communication system is forced on the practical stage of extremely large number of radio channels and is required to reduce occupancy of coverage area for each channel. Compander have prevented from such degradation of speach quality via reducing transmission power as fading and thermal noise. In this paper, a nobel compander is proposed with basis on Short Time DFT (ab. in ST-DFT) which consists of N/2-1 sub-module along the frequency index of the ST-DFT. Both the configuration and frequency responses of the ST-DFT multi-channel feedforward compander (ab. in MC-FF compander) are discussed through computer simulation on CRAY X-MP/14se at AIT.
