Title
Flexible Probabilistic Shaping RoF Signal Transmission With Adjustable ACO.
Abstract
We first propose and experimentally demonstrate an optical multi-carrier generation system based on probabilistic shaping, which can dynamically modify the frequency and probability in the time and frequency domains. In this paper, the variability of the adjustable crystal oscillator is used to realize the dynamic adjustment of local vibration frequency and the change of the frequency of optical millimeter wave (MMW). On the other hand, the multi-probability mapping is carried out through probability shaping. In this way, the MMW with multiple frequencies and probabilities is obtained. The frequency-hopping multi-carriers are generated into three groups by using 20, 25, and 30 GHz as the local frequency and the BER of 20, 40, and 60 GHz under a different information entropy (3.15, 3.3, 3.45, 3.6, 3.75, and 3.9 bits/symbol) are measured. Through quadrature amplitude modulation, the transmission rate of 40 Gb/s can be realized. The experimental results indicate that the scheme has the advantages of higher flexibility and low cost, which can be applied to the approaching era of the fifth generation (5G) and the development of super 5G in the future.
