摘要： Bit-error rate measurements for ON-OFF keying modulation at multigigabit per second rates over a V-band wireless link are presented. Serial data-rates from 2.5 to 20 Gb/s were studied for a 231-1 bit random sequence. Error-free data transfer over a 0.3-m link was achieved at up to 10 Gb/s. Acceptable bit-error rates, <10?5 and 10?3, were measured at up to 1.5 m for 10- and 15-Gb/s data-rate, respectively. The performance was achieved using a transmitter that consists of an integrated wavelet generator, whereas the receiver was built from off-the-shelf waveguide components. The results demonstrate that very high data-rates may be achieved using binary modulation and short symbols generated in an efficient V-band transmitter. The system is benchmarked against state-of-the-art transceiver systems with multigigabit per second data-rates.

[IEEE 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Huangshan, China (2019.8.5-2019.8.8)] 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Performance evaluation for polarization shift keying modulation in atmospheric turbulence channel
摘要： The exponentiated Weibull (EW) distribution is adopted for all turbulence strengths when aperture averaging technology is applied. Firstly, the closed expression of the average bit error rate (BER) of a free space optical (FSO) system using polarization shift keying (POLSK) modulation under EW atmosphere turbulence model is derived. Then the effects of aperture averaging under different turbulence conditions described by the EW distribution are numerically studied with computer simulation, and the average BER of POLSK modulated system is compared with that of an on-off-keying (OOK) system. Numerical results show the effects of aperture averaging on the average BER under different turbulence strengths. The POLSK modulated FSO systems can offer better BER performance compared to OOK scheme.
