High level architecture evolved modular federation object model
Wenguang Wang, Yongping Xu, Xin Chen +2
To improve the agility, dynamics, composability, reusability, and development efficiency restricted by monolithic Federation Object Model (FOM), a modular FOM was proposed by High…
Doppler Spread Estimation by Tracking the Delay-Subspace for OFDM Systems in Doubly Selective Fading Channels
Xiaochuan Zhao, Tao Peng, Ming Yang +1
A novel maximum Doppler spread estimation algorithm for OFDM systems with comb-type pilot pattern is presented in this paper. By tracking the drifting delay subspace of time-varyin…
