In group communication, users often have different access rights to multiple data streams. Based on the access relation of users and data streams, users can form partially ordered...
Abstract--This work presents a channel model for the broadband characterization of power lines in presence of time variation of the loads. The model is characterized by taking into...
—Modulation techniques have attracted increasing attention in optical wireless communications. Basic schemes such as on off keying (OOK), pulse amplitude modulation (PAM) and pul...
