On the use of UWB Radio Interface for EHF satellite communications

In this work authors investigate the use of IR (Impulse Radio) UWB (Ultra-Wide Band) technique for satellite communications at frequency bands beyond Q/V bands. In particular, the paper shows how an IR UWB communication system is sensitive to typical hardware non-idealities at those frequency bands and compares its performance with the ones of a more classical continuous wave communications system with FSK (Frequency Shift Keying) modulation. Simulation results show that BER (Bit Error Rate) performance for IR-UWB Payload (P/L) architecture operating in W band (with same data rate and bandwidth occupation) are better than a 2-FSK scheme operating at same frequencies range and considering Dirty RF (Radio Frequency) effects.
