   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :CLEMENT RANJITH ANTHIKKAD & IRFAN AHMED BAIG; [2013]
   Nyckelord :Orthogonal Frequency Division Multiplexing OFDM ; Peak-to-Average Power Ratio PAPR ; Complementary Cumulative Distribution Function CCDF ; Partial Transmit Sequence PTS ; Tone Reservation TR .;

   Sammanfattning : This paper presents a new hybrid PAPR reduction technique for the OFDM signal, which combines a multiple symbol representations method with a signal clipping method. The clipping method is a nonlinear PAPR reduction scheme, where the amplitude of the signal is limited to a given threshold. LÄS MER

   Sammanfattning : Multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) technology is one of the most attractive candidates for fourth generation (4G) mobile radio communication. It effectively combats the multipath fading channel and improves the bandwidth efficiency. LÄS MER
