Pre-processing filter design at transmitters for IBI mitigation in an OFDM system被引量：1
《Journal of Systems Engineering and Electronics》2013年第5期722-728,共7页Xia Wang Lei Wang 
supported by the National Natural Science Foundation of China(60902045);the National High-Tech Research and Developmeent Program of China(863 Program)(2011AA01A105)
In order to meet the demands for high transmission rates and high service quality in broadband wireless communication systems, orthogonal frequency division multiplexing （OFDM） has been adopted in some standards. Ho...

A Novel MLT-based ETF-OFDM System for Anti-Jamming Communications
《Chinese Journal of Electronics》2011年第4期719-724,共6页SHANG Yong FENG Xiaotao 
Previous research has shown that the Expanded time-frequency OFDM （ETF-OFDM） system has good performance in anti-jamming communication. In this paper, a novel Lapped transform-based ETF- OFDM system is proposed with...

Adaptive Spreading Code Assignment for an Expanded Time-Frequency OFDM System with a Zero-forcing Equalizer被引量：1
《Chinese Journal of Electronics》2011年第2期312-316,共5页WU Bo SHANG Yong XIANG Haige 
The Expanded time-frequency （ETF-） OFDM system uses the two-level spreading technology for data transmissions. This system has shown to be robust against the narrowband jamming in flat fading channels. However, in m...
