This paper is concerned with the joint estimation of phase noise and time-varying channel responses in full-duplex multiple-input multiple-output (MEMO) orthogonal frequency division multiplexing (OFDM) systems. The time-variation of phase noise and multipath MIMO channel responses gives rise to the identiflability problem of estimating a large number of unknowns which is much greater than the number...
This paper studies the problem of frequency-and time-selective (doubly selective) channel estimation in full-duplex multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. In particular, the maximum-likelihood (ML) principle is employed to formulate a pilot-aided channel estimation algorithm. To reduce the number of doubly selective channel parameters to be...
This paper is concerned with multiuser downlink transmissions in the presence of inter-cell interference (ICI). In the considered system, precoding at base stations (BS) and postcoding at users are jointly determined to manage both inter-user interference (IUI) and ICI under mean square error (MSE) criterion. Unlike zero-forcing based precoding, the proposed MSE-based precoding scheme still work as...
This paper studies the problem of scheduling, preceding and limited feedback design for the emerging 3GPP-LTE systems over time-and frequency-selective (doubly selective) channels. In particular, greedy scheduling with zeroforcing (ZF) precoding is considered for the doubly selective multiuser multiple-input single-output (MISO) orthogonal frequency division multiplexing (OFDM) downlink channels....
This paper studies the problem of limited feedback design for heterogeneous multiuser transmissions over time- and frequency-selective (doubly selective) multiple-input multiple-output (MIMO) downlink channels. In limited feedback design over the channels, the discrete prolate spheroidal basis expansion model (DPS-BEM) is used as a fitting parametric model for capturing the time-variation of the multiuser...
