Advanced speech coding methods using digital signal processor
Zajíček, Marek ; Sysel, Petr (referee) ; Smékal, Zdeněk (advisor)
This master thesis describes the practical usage of AMR-WB (Adaptive Multi Rate - Wide Band) codec and its implementation on a digital signal processor which is integrated in functional voice communication system Siemens HiPath 4000. The first part is focused on the complete codec description, especially on an encoder and decoder. The second part partly describes signal processors and then is followed by the practical part of the implementation which is solved from the preliminary activities up to the optimalization of the final functional solution.

Modern methods speech coding for telecommunication network transmission
Zajíček, Marek ; Rajmic, Pavel (referee) ; Smékal, Zdeněk (advisor)
This bachelor's thesis describes the usage of AMR-WB (Adaptive Multi-Rate Wide-Band) codec in telecommunication networks, especially in mobile networks and VoIP technologies. There are also described basic principles of coding and resolved characteristics of this system in detail, especially advantages, disadvantages and the way of practical usage of codecs. This bachelor's thesis was processed by using LATEX application.
