We formulate the optimum multicarrier multiuser detector to be deployed in asynchronous multitone multiuser systems.
We present simulated error rate and code delay/amplitude tracking performance for two recently developed detectors: the adaptive whitened matched filter, and the quasi-synchronous decorrelator, Rap
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.
