The usage of the millimeter wave (MMW) band in the 5th generation (5G) networks relies on beamforming to compensate the strong path-loss suffered at higher frequencies.
The advantage of large antenna systems relies on the acquisition of the channel state information at the base station, which is difficult for frequency-division-multiplexing systems, as the pilot o
The advantage of large antenna systems relies on the acquisition of channel state information (CSI) at the base station (BS), which can be difficult especially for frequency-division-multiplexing (
In this paper, a novel channel estimation (CE) method is proposed for spatial modulation (SM), a unique single-stream multiple-input-multiple-output transmission technique.
We present inner and outer bounds for the multiple-input-multiple-output mutiple access channel with imperfect channel estimates.
Time-varying channel estimation is a well-known challenge for wireless communications on high-speed railways.
The location information of a mobile terminal has become more available due to the popularity of GPS-aided smartphones.
The fifth generation (5G) communication has recently attracted much interest.
Wireless communications in the low terahertz band (0.1 THz-1 THz) is a promising candidate to enable ultra-high-rate vehicular networks beyond 5G.
We study the performance of time-of-arrival (ToA) localization for an indoor office environment.
