1. 1. Evaluation and Compensation of Nonlinear Distortion in Multicarrier Communication Systems

   Författare :Ali Behravan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinearity; Multicarrier communication systems; peak-to-average power ratio;

   Sammanfattning : In modern wireless communication systems with increasing data transfer rateand mobility, designing efficient transceivers is a key issue. Among differentchallenges, nonlinearity of high power amplifiers is a problem that has to beovercome by means of adding extra hardware or using more efficient signalprocessing algorithms. LÄS MER
