Improving the Performance of OFDM Channel Estimation through Subspace Projecting and Tracking

Dong Liang,Cao Xiuying,Bi Guangguo

Strategic Study of CAE 2006, Volume 8, Issue 11,   Pages 86-93

Abstract:

The LS channel estimation of OFDM systems can be viewed as a noisy observation of the true channelprojecting is enforced, and the general framework to perform subspace projecting in the context of OFDM

A novel method for PAPR reduction of the OFDM signal using nonlinear scaling and FM Regular Article

Yi-hu Xu, Jung-Yeol Oh, Zhen-hao Sun, Myoung-Seob Lim,xuyh@ybu.edu.cn,mslim@jbnu.ac.kr

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 11,   Pages 1587-1594 doi: 10.1631/FITEE.1800438

Abstract: (OFDM) has been adopted as standard beginning with the 4 generation mobile communication system becauseHowever, a major disadvantage of OFDM is the non-constant envelope signal with a high (PAPR).The high peak signal in OFDM is distorted through a nonlinear amplifier, which causes bit error ratioThe time slot location and scaling ratio for where and how the high peak baseband OFDM signal is downscaledare transmitted using (FM) combined with OFDM, which requires less additional bandwidth than the previously
