A New Design Criterion of Radio Frequency Front-End Gain for Interference Cancellation Performance in Communication Systems

IEEE Open Journal of the Communications Society
Adaptive interference cancellation is an effective means to fulfill the anti-interference requirements of communication systems. The radio frequency (RF) front-end gain plays a crucial role since it determines the communication sensitivity and anti ...

Secure communications using interference alignment in MIMO interference channels

IEICE Communications Express, 2014
In recent years, the multiple-input multiple-output (MIMO) interference channels, where multiple pairs of a transmitter and a receiver having multiple antennas communicate in parallel, have been considered to maximize transmission capacity in a multiple communication environment.

Phase Characterization and Correction in a Hardware Implementation of an OFDM-Based System for VLC Applications

, 2023
Orthogonal frequency-division multiplexing (OFDM) systems have been widely implemented in guided and non-guided communications. Even though they are becoming a standard for popular technologies such as WiFi, their implementation in newly emerging ones is

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Efficient minimum blind area model for system and interference uncertainty

IET Microwaves, Antennas & Propagation
In the anti‐interference of broadband communication radio, interference cancellation performance is seriously affected by the uncertainty of the working frequency selection of the communication system and the direction of hostile interference. The closed‐
