Tomlinson-Harashima Precoding-Aided Multi-Antenna Non-Orthogonal Multiple Access
Jungho So, Youngchul Sung, Yong H. Lee
In this paper, Tomlinson-Harashima Precoding (THP) is considered for multi-user multiple-input single-output (MU-MISO) non-orthogonal multiple access (NOMA) donwlink. Under the hie…
Filter Design for Generalized Frequency-Division Multiplexing
Seungyul Han, Youngchul Sung, Yong H. Lee
In this paper, optimal filter design for generalized frequency-division multiplexing (GFDM) is considered under two design criteria: rate maximization and out-of-band (OOB) emissio…
A joint time-invariant filtering approach to the linear Gaussian relay problem
Cheulsoon Kim, Youngchul Sung, Yong H. Lee
In this paper, the linear Gaussian relay problem is considered. Under the linear time-invariant (LTI) model the problem is formulated in the frequency domain based on the Toeplitz…
Gaussian Relay Channel Capacity to Within a Fixed Number of Bits
Woohyuk Chang, Sae-Young Chung, Yong H. Lee
In this paper, we show that the capacity of the three-node Gaussian relay channel can be achieved to within 1 and 2 bit/sec/Hz using compress-and-forward and amplify-and-forward re…
Parallel Opportunistic Routing in Wireless Networks
Won-Yong Shin, Sae-Young Chung, Yong H. Lee
We study benefits of opportunistic routing in a large wireless ad hoc network by examining how the power, delay, and total throughput scale as the number of source- destination pai…
Capacity of the Gaussian Two-way Relay Channel to within 1/2 Bit
Wooseok Nam, Sae-Young Chung, Yong H. Lee
In this paper, a Gaussian two-way relay channel, where two source nodes exchange messages with each other through a relay, is considered. We assume that all nodes operate in full-d…
