Interference Alignment: A New Look at Signal Dimensions in a Communication Network (2011, background): “DoF of two hop layered interference networks are known when there is a relay that is equipped with sufficiently many antennas [16, 141] or when there is a large number (in many cases, approaching infinity) of distributed relays [11, 15, 38, 98, 122].”
Wireless Relay Communications with Unmanned Aerial Vehicles: Performance and Optimization (2011, background): “The advantages of using relays in more generic wireless network scenarios have been the subject of considerable interest recently (e.g., see [12], [ 13 ]).”
MIMO Configurations for Relay Channels: Theory and Practice (2007, methodology): “Based on the different CSI available at relays, we place MIMO relay channels into the following two categories [17]: 1) Non-coherent Relay Channels: where the kth relay only has full knowledge of the channel matrix Hk.”
Distributed Beamforming for Relay Networks Based on Second-Order Statistics of the Channel State Information (2008, methodology): “The common assumption used in [5] and [6] is that the perfect instantaneous channel state information (CSI) is available at the receiver as well as at the relaying nodes.”
Using Orthogonal and Quasi-Orthogonal Designs in Wireless Relay Networks (2007, background): “It is proved that with full channel information at the relays, the network capacity scales as , while without channel information at the relays, the capacity is a constant with respect to [7], [14].”
Spectral Efficient Signaling for Half-duplex Relay Channels (2005, background): “It can be shown that R[k +1] is a non-increasing sequence when choosing g[1] = g [8].”
Interference Alignment and the Degrees of Freedom of Wireless $X$ Networks (2009, background): “All transmitters and relays have an average power constraint of . Through an achievable scheme based on amplifyand-forward strategy at the relays, [ 8 ] shows that this network has degrees of freedom if the number of relays approaches infinity.”
MIMO Networks: The Effects of Interference (2008, methodology): “As another example of application, we evaluate the performance of MIMO relay networks in Rayleigh fading [34], [35].”
Network Beamforming Using Relays With Perfect Channel Information (2008, background): “Some assume channel information at the receiver but not the transmitter and relays , for example, the noncoherent amplifyand-forward protocol in [8, 9] and distributed space-time c oding in [10].”
Degrees of Freedom Region of the MIMO $X$ Channel (2008, background): “References [1]–[3] consider end-to-end channel orthogonalization with distributed sources, relays, and destination nodes and determine the capacity scaling behavior with the number of relay nodes.”
Interference Alignment and Spatial Degrees of Freedom for the K User Interference Channel (2007, background): “It can be argued that the most preliminary form of capacity characterization for a network is to characterize its degrees of freedom [5]–[11].”
Single and multiple relay selection schemes and their achievable diversity orders (2009, background): “However, for most pioneer AF schemes, every relay cooperates and each relay uses its maximum transmit power (e.g., [2,6, 7 ,10]).”
Spectral efficient protocols for half-duplex fading relay channels (2007, background): “We assume that there is no direct connection between the source and the destination (for example due to shadowing or too large separation) [1], [10] and that all terminals operate in halfduplex fashion [11], [12].”
