Description: OnPerformanceLimitsofDFTSpreadOFDMSystems
DFT Spread OFDM has been proposed recently to
reduce the Peak to Average Power Ratio (PAPR) of conventional
OFDM transmission. Besides PAPR reduction, an important
implication of DFT Spreading is that the independent parallel
sub-channels between the sub-carriers cease to exist. This in
turn leads to difference in its performance limits as compared to
the conventional OFDM system. This paper analyzes the error
probabilities of DFT Spread OFDM systems, and derives their
analytical closed form expressions for the AWGN, fading AWGN,
multipath and fading multipath channel scenarios. Simulation
results presented in last section confirm the validity of the derived
analytical expressions. Platform: |
