Low-Latency MAC Design for Pairwise Random Networks
Irshad A. Meer, Woong-Hee Lee, Mustafa Ozger +2
Feasibility of using unlicensed spectrum for ultra reliable low latency communications (URLLC) is still a question for beyond 5G wireless networks. Low latency access to the channe…
Sparse Channel Estimation in Wideband Systems with Geometric Sequence Decomposition
Woong-Hee Lee, Ki Won Sung
The sparsity of multipaths in the wideband channel has motivated the use of compressed sensing for channel estimation. In this letter, we propose a different approach to sparse cha…
Noise Learning Based Denoising Autoencoder
Woong-Hee Lee, Mustafa Ozger, Ursula Challita +1
This letter introduces a new denoiser that modifies the structure of denoising autoencoder (DAE), namely noise learning based DAE (nlDAE). The proposed nlDAE learns the noise of th…
Geometric Sequence Decomposition with -simplexes Transform
Woong-Hee Lee, Jong-Ho Lee, Ki Won Sung
This paper presents a computationally efficient technique for decomposing non-orthogonally superposed geometric sequences. The method, which is named as geometric sequence deco…
Deep Learning Based NLOS Identification with Commodity WLAN Devices
Jeong-Sik Choi, Woong-Hee Lee, Jae-Hyun Lee +2
Identifying line-of-sight (LOS) and non-LOS (NLOS) channel conditions can improve the performance of many wireless applications, such as signal strength-based localization algorith…
