We propose receiver architecture for FTN signaling transmission in the DVB-S2 standard. Typically, ISI- free condition has been assumed for DVB-S2 receiver design when satellite transponder model is absent. However, it's necessary to modify the recei

The recently approved mobile version of the Digital Video Broadcasting Return Channel via Satellite (DVB-RCS+M) foresees the use of direct sequence spectrum spreading (DS-SS) in the forward link. The addition of a spreading mode, on top of the conven

The railroad satellite channel is characterized by frequent signal outages due to tunnels, bridges and electrical trellises. While for medium/long tunnels the main option to offer reliable and uninterrupted connectivity deals with the adoption of gap
