In the first chapters a brief summary of algebraic geometry and coding theory is given. It is also demonstrated, how well known classed of codes, especially Reed-Solomon codes, can be constructed as special cases of algebraic geometric codes. The Skorobogatov-Vl{\u a}du{\c t} and Duurmsa decoding algorithms are presented in detail. As part of this diploma thesis a tutorial implementation was done, which is presented at the end. =note= Diploma Thesis =sponsor= =keywords= Goppa code, Gilbert-Varshamov bound
