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

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.
