Research on performances of single sideband modulated OFDM signals in ROF optical transmission system
Published 2009-01-01“…A novel OFDM-ROF system using single sideband modulation technology in radio-over-fiber system to generate optical wave was proposed and experimentally demonstrated.The 2Gbit/s OFDM signal and a 10GHz RF clock were mixed.The mixed signals were applied to drive a double-arm intensity modulator to generate a single sideband signal which transmitted to base station（BS） over fiber and broadcasted by antenna after the optical OFDM signal was converted into electrical OFDM signal.The experiment results show that in 10GHz-ROF system,a 2Gbit/s OFDM signal transmitted over 200km SMF without wireless broadcasting only has 1dB power penalty.After being only transmitted over 8m wireless air distance it has 0.3dB power penalty.When the signal transmitted over both 200km SMF and wireless air distance of 8m,also can obtain a clear received constellation in the experiment.…”

Design of hybrid precoding with successive interference cancellation and alternating direction method of multipliers
Published 2021-05-01“…To solve the problem of large power consumption caused by a large number of phase shifter (PS) in millimeter wave multi-antenna systems, a new type of dynamic connection structure was designed.With the goal of maximizing spectrum efficiency, two hybrid precoding schemes, successive interference cancellation (SIC) and successive interference cancellation-alternating direction multiplier (SIC-ADMM), were proposed.In SIC scheme, the sum-rate problem was decomposed into multiple sub-rate problems of different radio frequency links, the analog part was solved by iteration, and the digital part was solved by a low-dimensional equivalent matrix.Based on SIC scheme, an improved SIC-ADMM scheme was further proposed by studying the multi-variable sub-rate problem to achieve rapid convergence and reduce computational complexity effectively.The simulation results show that the proposed schemes have good spectrum and energy efficiencies by comparison with the existing schemes, and are more suitable for large-scale antenna systems.In addition, when a certain percentage of PS is turned off, the proposed scheme can greatly improve energy efficiency by sacrificing a small amount of spectrum efficiency.…”
