A performance comparison of broadband complex modulated non return to zero raised cosine shaped and rectangular pulsed signals is analyzed on an all-electrical MMIC-based E-band wireless data transmission set up over a free space distance of 4.1 km. We successfully demonstrated a transmission of up to 12 Gbit/s in 4.05 GHz radio frequency bandwidth, whereat the difference between both pulse forms has been analyzed in terms of EVM and BER. Compared to a rectangular pulsed signal, a raised cosine filtered communication signal suffers more from linear and nonlinear effects caused by the transmission system due to inter symbol interference and stronger requirements on the exact sampling time.
