A Quantize-then-Estimate Protocol for CSI Acquisition in IRS-Aided Downlink Communication

no code implementations4 Aug 2023 Rui Wang, Zhaorui Wang, Liang Liu, Shuowen Zhang, Shi Jin

Different from the uplink counterpart where the BS possesses the pilot signals containing the CSI of all the users, in downlink communication, the distributed users merely receive the pilot signals containing their own CSI and cannot leverage the correlation in different users' channels revealed in [1].

Quick and Reliable LoRa Physical-layer Data Aggregation through Multi-Packet Reception

no code implementations13 Dec 2022 Lizhao You, Zhirong Tang, Pengbo Wang, Zhaorui Wang, Haipeng Dai, Liqun Fu

Trace-driven simulation results show that the symbol demodulation algorithm outperforms the state-of-the-art MPR decoder by 5. 3$\times$ in terms of physical-layer throughput, and the soft decoder is more robust to unavoidable adverse phase misalignment and estimation error in practice.
