Cancelamento de Distorções Não Lineares em Sistemas OFDMA com Detecção Multiusuário

Inthispaper,westudyandanalysetheperformance oftheIterativeCorrectionHardDetectiontechniqueforcancellation of nonlinear distortions in OFDMA communication systems. This technique was developed and widely tested for OFDM systems.However,tothebestofourknowledge,theapplicationof this technique in OFDMA systems is unexplored in the literature. The application of this technique in OFDMA systems requires a multiuser detection for estimating and canceling the distortions introduced by the power amplifier.
