A Low Complexity Learning-based Channel Estimation for OFDM Systems with Online Training
Kai Mei, Jun Liu, Xiaoying Zhang +3
In this paper, we devise a highly efficient machine learning-based channel estimation for orthogonal frequency division multiplexing (OFDM) systems, in which the training of the es…
Peak-to-Average Power Ratio Analysis for OFDM-Based Mixed-Numerology Transmissions
Xiaoran Liu, Lei Zhang, Jun Xiong +3
In this paper, the probability distribution of the peak to average power ratio (PAPR) is analyzed for the mixed numerologies transmission based on orthogonal frequency division mul…
PAPR Reduction Using Iterative Clipping/Filtering and ADMM Approaches for OFDM-Based Mixed-Numerology Systems
Xiaoran Liu, Xiaoying Zhang, Lei Zhang +4
Mixed-numerology transmission is proposed to support a variety of communication scenarios with diverse requirements. However, as the orthogonal frequency division multiplexing (OFD…
High-precision timing and frequency synchronization method for MIMO-OFDM systems in double-selective channels
Jun Liu, Kai Mei, Xiaochen Zhang +3
In this letter, a novel synchronization method for MIMO-OFDM systems is proposed. The new approach has an accurate estimate of both symbol timing and large frequency offest. Simula…
