Although cyclostationary analysis of OFDM signals has been widely explored for spectrum sensing and signal identification, the associated high computational complexity requires additional processing and detection time, which further prevents the related techniques from fulfilling the demands of real-time military applications. In addition, recognizable and distinctive features of an OFDM signal in...
System performance of mobile wireless communications is limited by fast channel variations, which are mostly due to the mobility of user terminals and scatterers. In order to obtain the optimal system performance, precise knowledge of the channel variations is often needed through channel prediction. A new cluster-based time-domain predictor with improved performance is proposed in this paper. Our...
