In this paper, we develop a low-complexity channel estimation for hybrid millimeter wave
(mmWave) systems, where the number of radio frequency (RF) chains is much less than the …

Millimeter wave (mmWave) systems will likely employ large antenna arrays at both the
transmitters and receivers. A natural application of antenna arrays is simultaneous …

Channel estimation for downlink millimeter wave (mmWave) multiuser multiple-input-
multiple-output (MU-MIMO) communications over a time-varying channel is demandingly …

We propose new hybrid precoding schemes for the downlink transmission in a multiuser
millimeter wave (mmWave) system over frequency selective channels. In the system, the …

Millimeter-wave communication in the 60-GHz band requires large antenna arrays at both
the transmit and receive terminals to achieve beamforming gains, in order to counteract the …

Antenna arrays will be an important ingredient in millimeter-wave (mmWave) cellular
systems. A natural application of antenna arrays is simultaneous transmission to multiple …

In millimeter-wave (mmWave) systems, antenna architecture limitations make it difficult to
apply conventional fully digital precoding techniques but call for low-cost analog radio …

Millimeter wave (mmWave) cellular systems will enable gigabit-per-second data rates
thanks to the large bandwidth available at mmWave frequencies. To realize sufficient link …

Configuring the hybrid precoders and combiners in a millimeter wave multiuser multiple-
input multiple-output system is challenging in frequency selective channels. In this paper, we …

We consider the problem of uplink channel estimation for millimeter wave (mmWave)
systems, where the base station (BS) and mobile stations (MSs) are equipped with large …
