Resumo: The aim of this research is to present a performance comparison of series PAPR reduction techniques. The analyzed techniques are based in selective mapping schemes (SLM), partial transmission sequence (PTS) and Walsh-Hadamard transform (WHT). Altogether, three SLM derivations are evaluated: SLM using maximum length sequences, SLM using Hadamard sequences and SLM using sequences with complexes values. This research presents, as contribution, a technique for reducing PAPR, which consist in a junction of the PTS and SLM techniques, henceforth referred to as PTSModified. Thus, a total of six techniques are evaluated in this study. In this study, there is a detailed description of each these techniques for PAPR control and also, is presented the efficiency of reduction of PAPR in each technique. This is done by study of probability density function of PAPR, acquired by computer simulation for each case. Further of PAPR reduction, this study also analyses the effect of these techniques in symbol error probability in non-linear AWGN channels.

As t?cnicas analisadas s?o baseadas em esquemas de mapeamento seletivo (SLM), transmiss?o de sequ?ncia parcial (PTS) e transformada de Walsh-Hadamard (WHT). Ao todo, tr?s deriva??es de esquemas SLM s?o avaliadas: SLM usando sequ?ncias de m?ximo comprimento, SLM usando sequ?ncias de Hadamard e SLM usando sequ?ncias com valores complexos. Al?m de avaliar o PTS convencional, este trabalho apresenta, como contribui??o, uma t?cnica de redu??o da PAPR, que consiste da jun??o das t?cnicas PTS e SLM, doravante denominada PTSModificado. Desta forma, um total de seis t?cnicas s?o avaliadas neste trabalho. No trabalho existe uma descri??o detalhada de cada uma destas t?cnicas de controle da PAPR e, tamb?m, ? apresentada a efici?ncia de redu??o da PAPR das mesmas. Isto ? feito atrav?s do estudo da fun??o densidade de probabilidade da PAPR, levantadas por meio de simula??o computacional para cada caso. Al?m da redu??o da PAPR, este trabalho tamb?m analisa o efeito destas t?cnicas na probabilidade de erro de s?mbolo em canais AWGN n?o-lineares.Submitted by Tede Dspace (tede@inatel.br) on 2017-02-22T12:56:37Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Dissertacao V.
