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: |

Description: To combat high PAPR, one intuitive solution is to adopt amplifiers to have larger trade-off range. However, these types of amplifiers are generally expensive and have low efficiency-cost, and therefore are of no practical use. On the other side, certain algorithms were introduced and been proved have a good performance of high PAPR reduction. Hence, in this thesis, some currently promising PAPR reduction methods are studied and compared. The performance of these reduction schemes are evaluated by using simulation software, Matlab.

Description: dct precoded SLM method for PAPR reduction
High Peak to Average Power Ratio (PAPR) is still a
most important challenge in Orthogonal Frequency Division
Multiplexing (OFDM) system. In this paper, we propose a
Discrete Cosine Transform (DCT) precoding based SLM
technique for PAPR reduction in OFDM systems. This
technique is based on precoding the constellation symbols with
DCT precoder after the multiplication of phase rotation factor
and before the Inverse Fast Fourier Transform (IFFT) in
SLM-OFDM System. Platform: |
