Equalizer design in frequency domain of SC-FDE system(SC-FDE系统的频域均衡器设计)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2007
在介绍了频域均衡单载波(SC-FDE)系统的特点和工作原理基础上,提出了几种适合于SC-FDE系统的频域均衡器结构:迫零均衡器、最小均方误差均衡器、最小二乘均衡器、最小均方误差-判决反馈均衡器、频域自适应均衡器以及采用OFDM信号处理方式的自适应均衡器.分别在SUI-3和SUI-5信道条件下通过Matlab平台上的性能仿真对提出的几种均衡嚣进行了比较,得出了一些有实际意义的结论.

On SC/FDE Block Transmission with Reduced Cyclic Prefix Assistance

open access: green2006 IEEE International Conference on Communications, 2006
For conventional CP-assisted (Cyclic Prefix) SC/FDE implementations (Single- Carrier/Frequency-Domain Equalization), as well as for OFDM implementations (Orthogonal Frequency Division Multiplexing), the CP length is known to be selected on the basis of the expected maximum delay spread.

The Therapeutic Potential of Farm Dust Extracts in a Mouse Model of Eosinophilic Inflammation. [PDF]

open access: yesAllergy
Farm dust extract (FDE) treatment reduces airway eosinophilia, mucus overproduction, and MHC‐II expression on DCs, limiting antigen presentation and Th2 inflammation. It increases PD‐L1 on DCs, promoting T cell deactivation. Additionally, FDE enhances Tregs and upregulates CTLA‐4, reinforcing suppression.
