description |
Orthogonal Frequency Division Multiplexing (OFDM) is an attractive
modulation method for channels with a non-flat frequency response. as it saves the need
for complex equalizers. However. its main disadvantage is the high peak-to-average
power ratio (PAPR) of the output signal. which may take values within a range that is
proportional to the number of carriers in the system. As a result, a linear behavior of the
system over a large dynamic range is needed and therefore the efficiency of the output
amplifier is reduced. Many methods have been proposed to reduce the PAPR of the
OFDM signal. among them a clipping technique which has been focused and
investigated.OFDM signal, among them a clipping technique which has been focused and
investigated.
This thesis proposes a new scheme to reduce the PAPR. We name it Off technique.
Further the effects of clipping scheme as well as the new scheme on the OFDM system
performance in terms of Bit Error Rate (BER) and PAPR reduction is investigated. The
results obtained indicate that both parameters, i .e. the reduction in PAPR and BER of
this scheme were worse than those of the Clipping Scheme. In conclusion, results
indicate that Off Technique does not offer a better solution to PAPR reduction in the
OFDM system. |
