Abstract
We present results of simulation of the low-bit rate speech transmission system in channel with common Rayleigh fading. The system uses the code-excited linear voice prediction (CELP) and the channel errors correction. Quality of the speech restoration provided by the system was estimated with the help of two tests. The first one is the well known intelligibility Diagnostic Rhyme Test (DRT) [1] and the second one is the Mean Opinion Score (MOS) [1]. The system considered appears to be rather robust i.e., demonstrates high noise and fading immunity and provides good speech quality for the bit-rate 4.8 kbs in channels with the bit-error rate not exceeding 10-2.
