  • Lee, Kanghee; Kwon, Hyuck M.; Kim, Deawon; Shim, Yeonggyu; Park, Hyuncheol; Lee, Yong H.; Hyun, Inha (IEEE, 2013)
    This paper proposes amplify-and-forward (AF) relay matrices for a one-source-one-destination pair and cooperative distributed N relay nodes under three adverse wireless relay communication environments: (1) broadband noise ...
  • Lee, Kanghee; Kwon, Hyuck M.; Kim, Hyunggi; Sawan, M. Edwin; Park, Hyuncheol; Lee, Yong H. (IEEE, 2012-09)
    This paper considers an amplify-and-forward (AF) relay scheme for M-source-M-destination pairs and N relay nodes. Cooperative minimum mean square error (MMSE) strategies for wireless relay networks under both a jamming ...
  • Lee, Kanghee; Kwon, Hyuck M.; Kim, Hyunggi; Lee, Sangku; Shim, Yeonggyu; Park, Hyuncheol; Lee, Yong H. (IEEE, 2013)
    This paper presents both cooperative and noncooperative amplify-and-forward (AF) relay networks consisting of a one-source-one-destination pair and N-relays under receiver power constraint (RPC) at the destination. The ...
  • Lee, Kanghee; Yang, Jie; Kwon, Hyuck M.; Park, Hyuncheol; Lee, Yong H. (IEEE, 2014-05)
    This paper presents a closed form of an optimal cooperative amplify-and-forward (AF) relay amplifying matrix for a distributed relay network of M-source-M-destination pairs and N relays, called a cooperative distributed ...
  • Lee, Kanghee; Kwon, Hyuck M.; Kim, Hyunggi; Park, Hyuncheol; Lee, Yong H. (IEEE, 2012-11)
    This paper presents an amplify-and-forward (AF) relay scheme for M-source-M-destination pairs and N relay nodes. Cooperative minimum mean square error (MMSE) and zero-forcing (ZF) strategies for wireless relay networks ...
  • Lee, Kanghee; Kwon, Hyuck M.; Yang, Jie; Sawan, M. Edwin; Park, Hyuncheol; Lee, Yong H. (IEEE, 2013)
    This paper addresses a more practical relay network consisting of a mobile source, multiple distributed mobile amplify-and-forward (AF) relays, and a mobile destination node. It considers an appropriate channel model between ...
  • Lee, Kanghee; Kwon, Hyuck M.; Jo, Mansik; Park, Hyuncheol; Lee, Yong H. (IEEE, 2012-09)
    This paper studies minimum mean square error (MMSE)-based full-duplex relay processing matrices and source/destination beamforming vectors under perfect channel state information by imposing constraints on the transmit ...
  • Lee, Kanghee; Kwon, Hyuck M.; Yang, Jie; Sawan, M. Edwin; Park, Hyuncheol; Lee, Yong H. (IEEE, 2013)
    This paper studies amplify-and-forward (AF) relay strategies for two-way wireless relay networks consisting of two sources with a single antenna and multiple relays with a single antenna. The closed form of relay amplifying ...
  • Kim, Hyunggi; Kwon, Hyuck M.; Lee, Kanghee; Shim, Yeonggyu; Park, Hyuncheol; Lee, Yong H. (IEEE, 2013)
    A cooperative amplify-and-forward (AF) wireless relay scheme consisting of M sources, N relays, and L destinations all equipped with a single antenna is studied in this paper. The main objective is to design jointly and ...
  • Kim, Kwanghoon; Park, Hyuncheol; Kwon, Hyuck M. (IEEE, 2012-05)
    As channel time-variation increases, orthogonality among subcarriers in an orthogonal frequency division multiplexing (OFDM) symbol can be destroyed because of the relatively long symbol period, whereupon intercarrier ...
  • Lee, Kanghee; Kwon, Hyuck M.; Yang, Jie; Sawan, M. Edwin; Park, Hyuncheol; Lee, Yong H. (IEEE, 2013)
    This paper studies both cooperative and noncooperative amplify-and-forward (AF) wireless relay strategies with power constraints at the source and at the relays. The main objective is to design jointly and iteratively the ...
  • Lee, Kanghee; Kwon, Hyuck M.; Sawan, M. Edwin; Shim, Yeonggyu; Park, Hyuncheol; Lee, Yong H. (IEEE, 2013)
    This paper assumes a practical channel model, called a cascaded Rayleigh fading channel, for a noncooperative distributed mobile relay network, which consists of one mobile source and one mobile destination, and multiple ...
  • Lee, Kanghee; Kwon, Hyuck M.; Xiong, Wenhao; Kim, Hyunggi; Feng, Shuang; Park, Hyuncheol; Lee, Yong H. (IEEE, 2012-10-01)
