A new FWHT‐CMF‐DFE based approach for channel equalization in CP‐free OFDM systems
IET Communications, 2021 Orthogonal frequency division multiplexing (OFDM) has been widely used in wireless communication systems due to its robustness against the frequency selectivity of fading channels. It provides optimal performance and it also meets the requirements of the

Scientific Programming, Volume 2021, Issue 1, 2021., 2021 Protein‐protein interactions (PPIs) in plants are crucial for understanding biological processes. Although high‐throughput techniques produced valuable information to identify PPIs in plants, they are usually expensive, inefficient, and extremely time‐consuming.

A New‐Trend Model‐Based to Solve the Peak Power Problems in OFDM Systems
Modelling and Simulation in Engineering, Volume 2008, Issue 1, 2008., 2008 The high peak to average power ration (PAR) levels of orthogonal frequency division multiplexing (OFDM) signals attract the attention of many researchers during the past decade. Existing approaches that attack this PAR issue are abundant, but no systematic framework or comparison between them exists to date.
