The purpose of this thesis is to study some cooperation strategies between computers in order to increment the system reliability without compromising extra resources. In order to achieve this aim research must be conducted on data sharing on the receiver side regarding symbols, which have to be selected by means of a suitable procedure involving the L-values of the information bits. Nonetheless, in a computer, real values can’t be used and it will be necessary to quantize careful these symbols, hence the analysis of different methods of quantization will be investigated, as well as the uniform quantization, the iterative Lloyd-Max’s algorithm for non-uniform quantization and the vector quantization. The results will we shown analysing the different throughput for a different quantization scheme for a given modulations, using Matlab.
