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: 峰值抵消算法的基本思想是：在OFDM信号上叠加一个由一系列加权参考函数组成的峰值抵消信号，通过抵消函数的选取以及权值计算，使得抵消信号尽可能消除超过门限的信号幅值。常见的参考函数分为脉冲函数和其他窗函数两类。- T. May, H. Rohling. Reducing the peak-to-average power ratio in OFDM radio transmission systems. IEEE Vehicular Technology Conference (VTC), May 1998, Ottawa Canada, 3: 2474-2478

Description: In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER. Also requires highly linear power amplifier which increases cost of the system. PAPR is ratio of peak power to average power of time domain complex baseband signal which is to be transmitted. We will discuss PAPR reduction techniques below.-In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER.

Description: Partial transmit sequences (PTS) is a class of
distortless PAPR reduction techniques for OFDM systems.
However, the high complexity of PTS remains a problem. In [5]
the authors show that the PAPR reduction performance of PTS is
not as good as that of another distortless technique-selected
mapping (SLM) with the same computational complexity. To
alleviate this problem, a novel selected PTS (S-PTS) method with
low complexity is proposed. The main idea is based on selecting
part of the candidate signals the overall signals, so as to
make a better tradeoff between PAPR reduction and
computational complexity. Simulation results demonstrate that
the PAPR reduction performance of S-PTS is better than that in
SLM when their overall computational complexities are identical-Partial transmit sequences (PTS) is a class of
