This paper describes the design and performance of a 64-channel equalization and blocking filter.
Traditional approaches in the analysis of downlink systems decouple the precoding and the channel estimation problems.
In this paper, we study the channel estimation problem for time division multiplex amplify-and-forward (AF) relay channels.
Today's wireless cellular systems are limited by inter-cell interference. Coordinated multi-point transmission and reception (CoMP) is a promising approach to cope with this problem.
To further increase spectral efficiency and reliability of future wireless communications systems, base station cooperation, or "coordinated multipoint (CoMP)", has become a major trend in physical
We propose and demonstrate the use of subcarrier/polarization-interleaved training symbols for channel estimation and synchronization in polarization-division multiplexed (PDM) coherent optical ort
The fifth generation (5G) wireless communication is currently a hot research topic and wireless communication systems on high speed railways (HSR) are important applications of 5G technologies.
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 (
