    • AF MIMO wireless relay networks under received power constraint 

      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 ...
    • Boundaries of Signal-to-Noise Ratio for Adaptive Code Modulations 

      Pinyoanuntapong, Krittetash; Goswami, Madhuprana; Habib, Ashfia Binte; Kwon, Hyuck M.; Pham, Khanh D. (IEEE, 2016)
      Adaptive code modulation (ACM) has been studied for last two decades to enhance the bandwidth and power efficiency in a bandwidth-constrained and power-constrained communication system environment. This paper studies how ...
    • Distributed AF mobile relay networks in adverse wireless communication environments 

      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 ...
    • Jamming statistics-dependent frequency hopping 

      Hannon, Matthew; Feng, Shaung; Kwon, Hyuck M.; Pham, Khanh D. (IEEE, 2016)
      This paper studies a jamming statistics-dependent frequency-hopping (FH) pattern generation scheme. Most existing FH patterns are determined by two encryption keys: (a) one for FH in the frequency domain, and (b) the other ...
    • Noncooperative AF schemes for wireless mobile networks under jamming environment 

      Ibdah, Yazan; Kwon, Hyuck M.; Ding, Yanwu; Lee, Kanghee (IEEE, 2011-11-07)
      Communication between mobile relays has recently gained much attention. In this paper, a novel optimal diagonal relay amplifying matrix based on the minimum mean square error (MMSE) criterion is proposed for mobile nodes. ...
    • Relay selection for af siso wireless relay networks under jamming environment with relay power constraint 

      Lee, Kanghee; Kwon, Hyuck M.; Xiong, Wenhao; Kim, Hyunggi; Lee, Sangku (IEEE, 2012-10-29)
      A noncooperative amplify-and-forward (AF) wireless relay network consisting of a one-source-one-destination pair and N relays is investigated. The objective of this paper is to analytically derive the explicit optimal ...
