Linear precoding for wireless multi-input multi-output (MIMO) transceivers has demonstrated substantial strength in cooperative relay networks for achieving high system throughput and performance. However, traditional precoder optimization critically assumes knowledge of channel state information (CSI) at source nodes. For linear MIMO source precoding(More)
In this paper we study the power control of multiuser orthogonal frequency division multiplexing (OFDM) transmissions in a heterogeneous network which features macro user equipments (MUEs) and pico user equipments (PUEs) sharing the same resource blocks (RBs) during downlink. We aim to maximize the sum capacity of PUEs while meeting the performance(More)
Traditional physical-layer (PHY)-based secret key generation schemes typically assume reciprocity of forward and reverse channels in order for facilitated shared secrecy. However, frequency-selective channels for frequency division duplex links as well as calibration difference of transceiver hardwares can invalidate reciprocity assumption and can cause(More)
