A PTS Optimization Scheme with Superimposed Training for PAPR Reduction in OFDM System
《Communications and Network》2014年第2期97-104,共8页Renze Luo Rui Li Xiaoqiong Wu Shuainan Hu Na Niu 
Partial Transmit Sequences (PTS) is an efficient scheme for Peak-to-Average Power Ratio (PAPR) reduction in Orthogonal Frequency Division Multiplexing (OFDM) system. It does not bring any signal distortion. However, i...

Sidelobe Suppression in CR-OFDM system by Adding Extended Data Carriers
《Communications and Network》2013年第3期327-332,共6页Tianwei Wen Yafeng Wang 
Out-band radiation is a severe problem for Cognitive Radio with OFDM system (CR-OFDM) which is caused by the sidelobe of OFDM signals. Lots of studies have been done on suppressing the sidelobe power and numerous meth...

An Iterative Maximum Likelihood Synchronization Method for OFDM System被引量:1
《Communications and Network》2013年第2期43-47,共5页Chi-Min Li Wei-Tse Sun 
OFDM system divides a wideband transmission bandwidth into several overlapped narrowband subcarriers to avoid the serious frequency selective fading problem. However, if Timing Offset (TO) and Carrier Frequency Offset...
