Abstract |
|
In modern communication systems, the number of users are increased rapidly to access the wired networks. Consequently the use of channel capacity has to be increased.G.729 is one of the widely used standard in ITU-T for Speech compression. Speech coding is the application of data compression of digital audio signal containing speech. Speech compression aims to compress the speech signal to attain maximum channel capacity with lower bit rate and highest quality. G.729 is one of the widely used standard in ITU-T for speech compression. The algorithm used for this is 8 kb/s speech coding algorithm. It is based on CS-ACELP( Conjugate Structure Algebric Code Excited Linear Prediction) coding technique. This algorithm predicts the next incoming signals by means of linear prediction. The CS-ACELP speech codec delivers quality of Speech equivalent to that of 32kb/s ADPCM for most operating conditions. |
