Cross-subcarrier precoder design for massive MIMO-OFDM downlink with symplectic optimization

引用

Science China(Information Sciences) 2025年

作者： Yu-Xuan zhang An-An LU Xiang-gen XIA Xi-Qi GAO National Mobile Communications Research Laboratory Southeast University Purple Mountain Laboratories Department of Electrical and Computer Engineering University of Delaware

We propose a cross-subcarrier precoder design(CSPD) for massive multiple-input multiple-output(MIMO) orthogonal frequency division multiplexing(OFDM) downlink. This work aims to significantly improve the channel estimation and signal detection performance by enhancing the smoothness of the frequency domain effective channel. This is accomplished by designing a few vectors known as the transform domain precoding vectors(TDPVs), which are then transformed into the frequency domain to generate the precoders for a set of subcarriers. To combat the effect of channel aging, the TDPVs are optimized under imperfect channel state information(CSI). The optimal precoder structure is derived by maximizing an upper bound of the ergodic weighted sum-rate(WSR) and utilizing the a posteriori beam-based statistical channel model(BSCM). To avoid the large-dimensional matrix inversion, we propose an algorithm with symplectic optimization. Simulation results indicate that the proposed cross-subcarrier precoder design significantly outperforms conventional methods.

＜正＞The reverse transcriptase （RT） is an attractive target for the development of new anti-AIDS drugs because its vital role in the replication cycle of HIV. In the last decade, a number of RT inhibitors were discovered and introduced in clinical practice. They are divided into two groups: nucleoside reverse transcriptase inhibitors （NRTIs） and non-nucleoside reverse transcriptase inhibitors （NNRTIs）. NNRTIs are a group of structurally diversed compounds. To date, many classes of NNRTIs have been identified, and three inhibitors, nevirapine, delavirdine, and efavirenz, have been approved for the treatment of HFV-1 infection. However, the therapeutic effectiveness of both classes of inhibitors is limited by rapid emergence of drug-resistant HIV-1 strains. So the development of novel, selective, potent and safe antiviral agents remains a high priority for medicinal chemistry research.
