Title
Power Control Optimization Method for Transmitted Signals in OFDM Communication Systems.
Abstract
Orthogonal frequency division multiplexing OFDM introduces large peak power of transmitted signals in time, which can result in significant signal distortion in the presence of nonlinear amplifiers. Partial transmit sequence PTS are well-known techniques for peak-power reduction in OFDM.ï¾ź However, the exhaustive search of phase factors in conventional PTS causes high computational complexity. In this paper, we present a suboptimal strategy for combining partial transmitted sequences that achieve good balance between computational complexity and power control performance. The simulation results show that the proposed algorithm can not only reduces the PAPR significantly, but also decreases the computational complexity
