Abstract [en]

The technological developments in digital communication systems increase the usable bandwidth of sound signals which results in increased intelligibility and naturalness of the signal. The emerging digital communication systems enable the use of wideband speech codec in a wide area of applications. Recognizing the need of high quality wide band speech codec, several standardization activities have been recently conducted. G.722 is one of the first wideband speech codec standards implemented in the telecommunication systems. In this thesis, after examining the G.722 wideband speech codec theoretically, a real time implementation of G.722 wideband speech codec has been developed on Blackfin BF533 DSP development kit from Analog Devices. Also, G.722 Codec is optimized by using assembler for BF533. As a result to the thesis, very good speech performance is obtained in real time implementation of G.722 and optimization increases the eciency of Blackfin BF533 DSP drastically.
