A Sensitivity Improvement Channel Estimation Algorithm for Direct Detection OQAM-OFDM Systems

摘要：

　　We propose and experimentally demonstrate a novel channel estimation algorithm based on the interference-approximation preamble structure and frequency-averaging scheme used in offset-QAM OFDM (OQAM-OFDM) system.The experimental results show that,in comparison with the traditional CE method,our scheme can achieve~1.5dB sensitivity improvement.
