Effect of element mutual coupling on the capacity of fixed length linear arrays (2002, background): “(It may be noted that even low correlation does not necessarily guarantee high capacity, particularly when the environment possesses “keyholes” [3]).”
Impact of antenna correlation on the capacity of multiantenna channels (2005, background): “• The keyhole channel, where H is given by the outer product of two random vectors with zero-mean independent entries [24, 25].”
A stochastic MIMO channel model with joint correlation of both link ends (2006, background): “Nevertheless, an instantaneous channel realization will have the same cross-shape (in the eigendomain) and, thus, its rank will be strictly limited to 2. The cross-like structure behaves in some sense like a keyhole channel, which is described in, e.g., [11], [ 22 ], and [23].”
Great expectations: the value of spatial diversity in wireless networks (2004, background): “Second, the presence of antenna correlation and the lack of scattering richness in the propagation environment reduce the achievable rates of spatial multiplexing techniques from their theoretical projections under ideal assumptions [58], [117].”
QuaDRiGa: A 3-D Multi-Cell Channel Model With Time Evolution for Enabling Virtual Field Trials (2014, background): “The median error at 5–dB SNR comparing noise-free with noisy 2 2 keyhole channels [41] is 7.”
Capacity limits of MIMO channels (2003, background): “Moreover, channels with very low correlation between antennas can still exhibit a “keyhole” effect where the rank of the channel gain matrix is very small, leading to limited capacity gains [12].”
Cochannel Interference Mitigation and Cooperative Processing in Downlink Multicell Multiuser MIMO Networks (2004, background): “, the keyhole problem [6]), a MIMO system will lose its capacity advantage (spatial multiplexing gain) over a SISO system, even though other advantages like diversity and array gains may still preserve.”
Multifunctional reconfigurable MEMS integrated antennas for adaptive MIMO systems (2004, background): “It is shown in [8] that in an outdoor propagation scenario the keyhole problem may be avoided by using a horizontally oriented transmitter array instead of vertically oriented array.”
The Multicell Multiuser MIMO Uplink with Very Large Antenna Arrays and a Finite-Dimensional Channel (2013, background): “However, in some specific scenarios, P is small, for example for keyhole channels [16].”
$N{\ast}$Nakagami: A Novel Stochastic Model for Cascaded Fading Channels (2007, methodology): “It is interesting to note that the double Rayleigh model has been recently used for keyhole channel modelling of multiple-in put multiple-output (MIMO) systems [18], [19].”
