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…
