This paper considers the transceiver design for uplink massive multiple-input multiple-output
(MIMO) systems with channel sparsity in the angular domain. Recent progress has shown …

In practical massive MIMO systems, a substantial portion of system resources are consumed
to acquire channel state information (CSI), leading to a drastically lower system capacity …

Massive MIMO has been regarded as a key enabling technique for 5G and beyond
networks. Nevertheless, its performance is limited by the large overhead needed to obtain …

In massive multiple-input multiple-output (MIMO) systems with hybrid analog/digital
architectures, large training overhead is required for conventional pilot-only methods to …

This paper proposes a spatially common sparsity based adaptive channel estimation and
feedback scheme for frequency division duplex based massive multi-input multi-output …

To fully exploit both multiplexing gain and array gain of massive multiple-input-
multipleoutput (MIMO), the channel state information must be obtained accurately at …

The use of one-bit analog-to-digital converter (ADC) has been considered as a viable
alternative to high resolution counterparts in realizing and commercializing massive multiple …

Accurate channel state information (CSI) at transmitter is of importance to sufficiently exploit
the merits of massive multiple input multiple output (MIMO). Because of the large amount of …

The knowledge of CSI at the BS (CSIT) is required to achieve the high spectrum efficiency
promised by massive MIMO. In Frequency-Division Duplex (FDD) Massive MIMO systems …

We study the problem of semi-blind channel estimation and symbol detection in the uplink of
multi-cell massive MIMO (multi-input multi-output) systems with spatially correlated time …
