Turbo codes and their applications in transmission technologies
Kuvik, Michal ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
Purpose of this work is to clarify problems of anti-error security with the help of turbo codes. This work can be divided into two parts. In the first part we look at the theoretical aspect of features of turbo codes, their coding and at various approaches of decoding secure messages for example SOVA and MAP, also at analyzing usage of turbo codes in promising transmission technologies. Second part is focused on creating an application with the help of software Matlab and on verifying attributes of this method in this software.

Turbo codes and their applications
Ploštica, Stanislav ; Krajsa, Ondřej (referee) ; Šilhavý, Pavel (advisor)
This Diploma thesis aims to explain the data coding using turbo codes. These codes belong to the group of error correction codes. We can reach the high efficiency using these codes. The first part describes process of encoding and decoding. There are describes parts of encoder and decoder. Principle of encoding and decoding demonstrate a simple example. The end of this part contains description of two most frequently used decoding algorithms (SOVA and MAP). The second part contains description of computer program that was made for using as teaching aid. This program was created in Matlab GUI. This program enables to browse error correction process step by step. This program contains graphic interface with many options and display results. In the third part is described program created in Matlab Simulink that was implemented into the TMS320C6713 kit and there is description of measuring procedure. For verification of efficiency of turbo codes was measured any parameters. Some of these parameters are: number of decoding iterations, generating polynoms and using of puncturing. The last part contains measured value and result evaluation.
