Noncooperative distributed wireless relay networks under channel uncertainty and power constraint

Lee, Kanghee; Kwon, Hyuck M.; Wang, Zuojun (IEEE, 2011-07-31)

This paper derives an optimum relay amplifying matrix for a wireless relay network under channel uncertainty and received power constraints at the destination node. To achieve this objective, an amplify-and-forward strategy ...
Optimum clustered pilot sequence for OFDM systems under rapidly time-varying channel

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 ...
