Abstract
In millimeter-wave (mmWave) wideband transmission, carrier phase noise is the primary limiting factor, especially for links employing Orthogonal Frequency Division Multiplexing (OFDM) signal, as orthogonality is sensitive to phase noise. This study employs two local oscillators with different phase noise (integrated rms jitter of 178 and 54 fs, respectively) to investigate the impact of carrier phase noise on wideband OFDM signal transmission at D-band. Experimental results indicate that phase noise has a significant impact on the capacity of OFDM transmission. In addition, the study shows that the number of OFDM subcarriers affects system performance, which is also linked to phase noise. Experimental results show that knowledge of phase noise can facilitate judicious choice of subcarrier number leading to optimized transmission capacity. For a bandwidth of 10 GHz OFDM signal, bit rates ranging from 44-56 Gbit/s are achieved, depending on the carrier phase noise and number of subcarriers.
