Abstract
While cellular and WLAN (Wireless Local Area Networks) at low frequencies (1–5 GHz) constantly struggle with the quasi-saturation of spectrum, the EHF band (30–300 GHz) has huge swathes of band available at no cost. The recently allocated 71–76 GHz and 81–86 GHz bands provide an opportunity for Line Of Sight (LOS) links for directional point-to-point ”last mile” links. This work focuses on the design and BER (Bit Error Rate) performance evaluation of a W band IR-UWB architecture based on an 85 GHz up-conversion stage of train of ns Gaussian pulses in terms of phase noise, and Low Noise Amplifier (LNA) and High Power Amplifier (HPA) distortions. Simulation results show that BER performance, in presence of RF non-linearities, for an IR-UWB transceiver architecture operating at W band (with same data rate and bandwidth) are better than a 2-FSK scheme working in a similar scenario.
