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: Multiple input multiple output techniques combined
with orthogonal frequency division multiplexing (MIMO-OFDM)
provide a promising approach for wireless systems. However, a
serious drawback of the OFDM system is the high peak-toaverage
power ratio (PAPR), which may severely affect the
power efficiency of RF power amplifiers. In this paper, we
propose a simple method to reduce the PAPR of MIMO-OFDM
signals based on the use of unused subcarriers. Instead of
processing the signals at each transmitter separately, a peak
cancelling signal is generated at one antenna and is then applied
to all the others with only simple modifications. Simulation has
shown that a minimum 2 dB reduction in PAPR can be achieved
for all transmit signals using this approach. As the signal
processing is nearly all done at a single transmitter, repetition of
the operations at each transmitter is avoided, and therefore the
overall cost of the system can be significantly reduced.

Description: In this paper, we have proposed a new PAPR reduction
technique in MIMO-OFDM systems. It achieves the result
which proves the PAPR of 2×2 MIMO-OFDM systems. The
parameters of the simulation are determined by standard IEEE
802.11n. From the simulation results, it is shown the proposed
method has better PAPR performance in this system.
Additionally, when the number of sub-blocks is increased, high
PAPR reduction performance can be obtained.

Description: In this section, the PAPR performance of the proposed
algorithms is shown. To evaluate the PAPR performance, the
CCDF is employed. The specification detail of simulation
parameters is given in TABLE I.
In Fig. 5 is shown the PAPR with a PTS method (U = 8) and
conventional PTS (U = 4) are improved 4.3 dB and 2.6 dB
from ordinary MIMO-OFDM signal when CCDF = 10− 4
respectively and Fig. 6 is shown the PAPR with an optimal
PTS method in case of 128 subcarriers.

Description: Selective mapping algorithm is proposed to reduce the peak-to-average power ration (PAPR) in MIMO-OFDM system.
It is proved that the conjugate symbols on two antennas have the same PAPR property with orthogonal space-time block coded (STBC). By using the characteristic, the computational
complexity cost and the side information (SI) is significantly
reduced compared with the concurrent SLM algorithm.
Simulation results demonstrate that the performance of the proposed algorithm outperforms the conventional concurrent
SLM algorithm.
