Abstract
IEEE 802.16e is a widely used standard for mobile broadband wireless access system and Orthogonal Frequency Division Multiplexing (OFDM) is employed in this system. So, it can perform well in anti-multipath fading and spectrum utilization. But there are also several critical problems, one of major drawbacks of this system is the high Peak-to-Average Power Ratio (PAPR) of the transmit signal. Thus the power amplifier in the transmitter requires a wide dynamic range or to be backed off, to prevent spectrum spreading issued from nonlinear distortion and BER rising issued from in-band distortion. But that will increase the system cost or lead to low power efficiency.
This paper firstly gives a brief of some important PAPR reduction techniques for multicarrier transmission, and then proposes a new PAPR scheme for 802.16e Wireless OFDM physical layer by using clipping and tone reservation (TR), and also considering the amplitude scale factor to reduce the computation cost and the system complexity. This new scheme has a very low out-of-band distortion, requires no side information and gains better PAPR performance by sacrificing fewer sub-carriers. At last, the performance of this new technique on PAPR reduction, BER, and spectrum efficiency has been analyzed through simulation derived from MATLAB. Furthermore, the simulation statistics has been compared with other related techniques.
