We propose a generalized architecture for the phase shifter network in hybrid analog/digital beamforming (BF), which can provide flexible tradeoff between the performance and implementation complex
Based on the characteristics of interference seen by a user in a cellular network, we present a very simple multiuser transmission scheme.
This paper formulates the power allocation policy that maximizes the region of mutual informations achievable in multiuser downlink OFDM channels.
For a multiuser interference channel with multiantenna transmitters and single-antenna receivers, by restricting each transmitter to a Gaussian input and each receiver to a single-user detector, co
We discuss the impact of downlink (DL) multiuser precoding granularities (in the frequency domain) on massive multiple-input-multiple-output (MIMO) systems.
The closed loop transmission schemes for multi user MIMO systems are usually sensitive to the delays in the feedback of channel state information (CSI).
In this paper, we investigate beamforming approaches for multiple access secrecy channels.
The ubiquity of the matrix inverse in multivariable linear systems can be attributed to the multivariable feedback loop control prevalent in such systems.
We describe the estimation of coherence, cross-spectra, transfer functions, and related multivariate time-series entitles using the multiple- window approach.
Remote rendering of video games for 3DTV becomes a hot topic with the emergence of 3D-enabled mobile devices and cloud-based services.
