چکیده
In this letter, we propose a novel and straightforward scheme for Q-band (33-50GHz) millimeter-wave signal generation enabled by Mach-Zehnder modulator (MZM)-based joint algorithm, which combines probabilistic shaping (PS) precoding technology, to enhance the anti-interference ability of transmission system. Based on proposed scheme, experimentally demonstrate 1.4-Gbaud 46-GHz PS-16-quadrature-amplitude-modulation (PS-16QAM) vector signals, showcasing improved bit-error-ratio (BER) in both standard single-mode fiber (SSMF) wireless cases. The exhibits clear advantage terms nonlinear interference suppression satisfies hard-decision forward-error-correction (HD-FEC) threshold with BER 3.8 × 10 −3 radio-over-fiber (RoF) systems.

Rule-based joint fuzzy and probabilistic networks
One of the important challenges in Graphical models is the problem of dealing with the uncertainties in the problem. Among graphical networks, fuzzy cognitive map is only capable of modeling fuzzy uncertainty and the Bayesian network is only capable of modeling probabilistic uncertainty. In many real issues, we are faced with both fuzzy and probabilistic uncertainties. In these cases, the propo...
متن کاملGolden Angle Modulation: Geometric- and Probabilistic-shaping
Quadrature amplitude modulation (QAM), deployed in billions of communication devises, exhibits a shaping-loss of πe/6 (≈ 1.53 dB) compared to the Shannon-Hartley theorem. With inspiration gained from special (leaf, flower petal, and seed) packing arrangements (so called spiral phyllotaxis) found among plants, we have designed a shape-versatile, circular symmetric, modulation scheme, the Golden ...

| A new combined precoding/shaping technique for fast digital transmission over twisted pair lines is proposed. Major advantages of this \dynamics shaping" are: Dynamics of the signal at the input of the decision device are reduced by a great amount. Thereby, A/D-conversion, adaptive equalization, and symbol timing are rather facilitated. A trade-oo between signal dynamics at the transmitter ou...
متن کاملBlind Equalization for Digital Cable Transmission with Tomlinson-harashima Precoding and Shaping
A new system concept for high-rate digital transmission over twisted pair lines with precoding is presented. To avoid retransmission of channel data, lters at the transmitter side are xed and designed for a reference application. Intersymbol interference caused by mismatch of designed lters and actual situation, is cancelled by an adaptive FIR equalizer. Implementation is thereby simpli ed cons...
